So if you want to spend less time studying, consider subscribing for easy access to all my time saving content. Ribosomes are an underrated hero of the cell and the average mammalian cell has about 10 million ribosomes! They are made of RNA and protein and their function in the cell is to read RNA and synthesize protein, very meta. Ribosomes have two major subunits, simply called, the large and small subunits. Both subunits contain protein and RNA. The RNA in ribosomes is called (not surprisingly) ribosomal RNA, or rRNA for short. In eukaryotic cells, ribosomes are synthesized in the nucleolus of the nucleus. The location of ribosomes in the cell determines where the protein they make ends up. Ribosomes free floating in the cytoplasm of the cell synthesize proteins to be used within the cell, while ribosomes bound to the Rough Endoplasmic Reticulum synthesize proteins that will end up outside the cell, either bound to the cell membrane or released from the cell as a signaling protein for example. Ribosomes synthesize protein in a process called translation where they “read” strands of mRNA and bring the right amino acids together to build a long polypeptide chain that that will eventually become a functioning protein. I’ll make a separate video about this whole process and link it below when it's ready. Now watch this test prep playlist if you have any exams coming up or watch these videos on topics you may find interesting. I also have some additional study resources linked in the description if you want to take you study to the next level. Thanks for watching, and I’ll catch you next time.

Ribosomes make Protein


What is a ribosome? A ribosome is an organelle found in plant, animal, and bacteria cells. They are very small yet very important because they make proteins. Ribosomes use a process called translation to make proteins. If you would like to learn more about proteins and their importance this video will help. 🤍 Transcript 🤍

mRNA Translation (Advanced)


The job of the mRNA is to carry the gene's message from the DNA out of the nucleus to a ribosome for production of the particular protein that this gene codes for. Originally created for DNA Interactive ( 🤍 ). TRANSCRIPT: The job of this mRNA is to carry the genes message from the DNA out of the nuceus to a ribosome for production of the particular protein that this gene codes for. There can be several million ribosomes in a typical eukaryotic cell these complex catalytic machines use the mrna copy of the genetic information to assemble amino acid building blokes into the three dimensional proteins that are essential for life. Lets see how it works. The ribosome is composed of one large and one small sub-unit that assemble around the messenger RNA, which then passes through the ribosome like a computer tape. The amino acid building blocks (that's the small glowing red molecules) are carried into the ribosome attached to specific transfer RNAs. That's the larger green molecules also referred to as tRNA. The small sub-unit of the ribosome positions the mRNA so that it can be read in groups of three letters known as a codon. Each codon on the mRNA matches a corresponding anti-codon on the base of a transfer RNA molecule.The larger sub-unit of the ribosome removes each amino acid and join it onto the growing protein chain. As the mRNA is ratcheted through the ribosome, the mRNA sequence is translated into an amino acid sequence. There are three locations inside the ribosome, designated the A-site, the P-site and the E-site. The addition of each amino acid is a three step cycle: First, the tRNA enters the ribosome at the A-site and is tested for a codon/anti-codon match with the mRNA. Next, provided there is a correct match, the tRNA is shifted to the P-site and the amino acid it carries is added to the end of the amino acid chain. The mRNA is also ratcheted on three nucleotides or one codon. Thirdly, the spent tRNA is moved to the E-site and then ejected from the ribosome to be recycled. As the protein synthesis proceeds, the finished chain emerges from the ribosome. It folds up into a precise shape, determined by the exact order of amino acids. Thus the Central Dogma explains how the four letter DNA code is - quite literally - turned into flesh and blood.

The ribosome has two subunits: small and large. - Several initiation factors, elongation factors, and release factors. These factors assist with initiation, elongation and termination of the process, respectively. Steps of the translation process: Initiation (eukaryotes) : The small ribosomal subunit binds to the initiator tRNA carrying the initiator amino acid methionine. This complex then attaches to the cap structure at the 5’ end of an mRNA and scans for the start codon AUG. The process is mediated by several initiation factors. At the start codon, the large ribosomal subunit joins the complex and all initiation factors are released. The ribosome has three sites: the A-site is the entry site for new tRNA charged with amino-acid or aminoacyl-tRNA; the P-site is occupied by peptidyl-tRNA - the tRNA that carries the growing polypeptide chain; the E-site is the exit site for the tRNA after it’s done delivering the amino acid. The initiator tRNA is positioned in the P-site. Elongation: A new tRNA carrying an amino acid enters the A-site of the ribosome. On the ribosome, the anticodon of the incoming tRNA is matched against the mRNA codon positioned in the A-site. During this proof-reading, tRNA with incorrect anticodons are rejected and replaced by new tRNA that are again checked. When the right aminoacyl-tRNA enters the A-site, a peptide bond is made between the two now-adjacent amino-acids. As the peptide bond is formed, the tRNA in the P-site releases the amino-acids onto the tRNA in the A-site and becomes empty. At the same time, the ribosome moves one triplet forward on the mRNA. As a result, the empty tRNA is now in the E-site and the peptidyl tRNA is in the P-site. The A-site is now unoccupied and is ready to accept a new tRNA. The cycle is repeated for each codon on the mRNA. Termination: Termination happens when one of the three stop codons is positioned in the A-site. No tRNA can fit in the A-site at that point as there are no tRNA that match the sequence. Instead, these codons are recognized by a protein, a release factor. Binding of the release factor catalyzes the cleavage of the bond between the polypeptide and the tRNA. The polypeptide is released from the ribosome. The ribosome is disassociated into subunits and is ready for a new round of translation. The newly made polypeptide usually requires additional modifications and folding before it can become an active protein.

RIBOSOMES structure and function | Video 5


Ribosomes are also called Ribonucleoparticles first time studied in 1955 by palad. Ribosomes are complexes of protein and RNA. The main function of ribosome is the protein synthesis. Roibosomes are not protein bounded and thus not concidered as organelle. Ribosomes are small dense granular structure present on ER and also in free form inside the cytoplasm. Ribosomes are almost composed of equal amount of RNA and Protein. Cells that have high rate of Protein synthesis have high number of ribosomes for example Pancreas cells of Human which make many digestive enzymes. Ribosomes are synthesized in the nucleolus of nucleus and have two subunits i.e. Small subunit and large subunit On the basis of size and sedimentation. Ribosomes are of two type number one is 70s ribosome present in Prokaryotic cell and in mitochondria and chloroplast in Eukaryotic cell. While the second type is 80s ribosomes which is present in Eukaryotic cell. The Function of Ribosome is the synthesis of protein with the help of mRNA and tRNA.

Rachel Green (Johns Hopkins U., HHMI) 1: Protein synthesis: a high fidelity molecular event


🤍 Talk Overview: In her first talk, Green provides a detailed look at protein synthesis, or translation. Translation is the process by which nucleotides, the “language” of DNA and RNA, are translated into amino acids, the “language” of proteins. Green begins by describing the components needed for translation; mRNA, tRNA, ribosomes, and the initiation, elongation, and termination factors. She then explains the roles of these players in ensuring accuracy during the initiation, elongation, termination and recycling steps of the translation process. By comparing translation in bacteria and eukaryotes, Green explains that it is possible to determine which components and steps are highly conserved and predate the divergence of different kingdoms on the tree of life, and which are more recent adaptations. Green’s second talk focuses on work from her lab investigating how ribosomes detect defective mRNAs and trigger events leading to the degradation of the bad RNA and the incompletely translated protein product and to the recycling of the ribosome components. Working in yeast and using a number of biochemical and genetic techniques, Green’s lab showed that the protein Dom34 is critical for facilitating ribosome release from the short mRNAs that result from mRNA cleavage. Experiments showed that Dom34-mediated rescue of ribosomes from short mRNAs is an essential process for cell survival in higher eukaryotes. Speaker Biography: Rachel Green received her BS in chemistry from the University of Michigan. She then moved to Harvard to pursue her PhD in the lab of Jack Szostak where she worked on designing catalytic RNA molecules and investigating their implications for the evolution of life. As a post-doctoral fellow at the University of California, Santa Cruz, Green began to study how the ribosome translates mRNA to protein with such accuracy. Currently, Green is a Professor of Molecular Biology and Genetics at the Johns Hopkins School of Medicine and an Investigator of the Howard Hughes Medical Institute. Research in her lab continues to focus on the ribosome and factors involved in the fidelity of eukaryotic and prokaryotic translation. Green is the recipient of a Johns Hopkins University School of Medicine Graduate Teaching Award as well as the recipient for numerous awards for her research. She was elected to the National Academy of Sciences in 2012.

Ribosome Structure and Function | What is a Ribosomes?


Ribosome structure and function are discussed in this video lesson. Its loctaion in a cell and site of synthesis are also explained. What is a ribosome? The ribosome is made up of two words, “ribo” meaning “ribonucleic acid” and “somes” from the Greek word “soma” meaning “body”. Ribosomes are small granular structures made up of ribonucleic acid (RNA) and protein, present in both eukaryotic and prokaryotic cells. The RNA present in ribosomes is known as ribosomal RNA, while proteins present in ribosomes are called ribosomal proteins. It was first studied by Palade in 1955. The ribosome is made up of two parts known as large and small subunits. Each subunit is made of some ribosomal RNA and many ribosomal proteins. The size of the ribosome is different in prokaryotic and eukaryotic cells.

Hi Everyone! Welcome To My Channel "Ali Academy Biology Lectures" About This Video ........................ In This Video Lecture You Will Learn Basic Concept Of Ribosomes Cell contains many tiny granular structures known as ribosomes. Palade (1955) was the irst person RNA. Ribosomes exist in two forms; either freely dispersed in cytoplasm or attached with RER as hence they are ribonucleo-proteins particles. The RNA present in ribosome is called ribosomal tiny granules. Each eukaryotic ribosome consists of two sub-units. The larger subunit sediments to study them. Eukaryotic ribosomes are composed of an almost equal amount of RNA and protein, subunits on attachment with each other form 80S particle. This attachment is controlled by the at 60S (S= Svedberg unit used in ultracentrifugation), while smaller subunit sediments at 40S. Two presence of Mg2+ ions. The ribosomes are attached to messenger RNA through small ribosomal subunit. A group of ribosomes attached to mRNA is known as polysome New ribosomes are assembled in the nucleolus of the nucleus from where they are transported to the cytoplasm via the pores in nuclear membrane. The factory of ribosome is the nucleolus, while that of protein synthesis is the ribosomes. About This Channel.....................

Ribosomen - Translation, Aufbau & Funktion | Studyflix


Was sind die Ribosomen und wie kannst du dir ihren Aufbau und ihre Funktion in der Zelle vorstellen?? Das alles erfährst du in diesem Video! Noch mehr kostenlose Videos gibt´s auf: 🤍 - Ribosomen kommen in Tierzellen , Pflanzenzellen und den Zellen der Prokaryoten vor. Du kannst sie dir als kleine Teilchen vorstellen, die aus Proteinen aufgebaut sind. Die Hauptaufgabe eines Ribosomes ist die Translation während der Proteinbiosynthese . Diese kannst du als das Ablesen von Informationen (mRNA ) und daraus die Bildung von Proteinen verstehen. Ein Ribosom (eng. ribosome) ist ein Zellorganell, das in allen Lebewesen vorkommt. Der Begriff „Ribosom“ kann aus dem englischen „ribonucleic acid“ (RNA) und dem griechischen „soma“ (Körper) abgeleitet werden. Wenn du ein Ribosom mit einem Mikroskop betrachtest, wird es dir als kleiner, ovaler Partikel auffallen. Es hat nur eine durchschnittliche Größe von ca. 20 bis 30 nm. Aufgebaut sind die Ribosomen aus mehreren Proteinen und der rRNA . Die Abkürzung rRNA steht für ribosomale Ribonukleinsäure. Sie wird innerhalb des Zellkerns gebildet. Wenn sich zwei oder mehr Ribosomen während der Translation aneinanderreihen, kannst du von einem Polysom oder Polyribosom sprechen. Dadurch kann die Translation von mRNA schneller ablaufen. Die mRNA wird auch als Boten-RNA bezeichnet. Du kannst sie dir als Botschafter vorstellen, die bestimmte DNA-Moleküle kopiert haben und an andere Zellorganellen weitergeben könne - 0:15 Einleitung 0:38 Aufbau 1:40 Aufbau in der Zelle 2:06 Ribosomen in Prokaryoten 2:45 Ribosomen in Eukaryoten 3:25 Aufgaben 4:10 Zusammenfassung - Weitere Informationen findest du auf Facebook: 🤍 oder auf unserer Webseite: 🤍 Hier geht´s zur Studyflix-App: - Play Store: 🤍 - Apple Store: 🤍 - Über uns: Studyflix ist eine junge, schnell wachsende E-Learning Plattform, die kostenlose Lernvideos für Dich zur Verfügung stellt.

Structure cellulaire 2 - ribosome, lysosome, mitochondrie, cytosquelette, centrosome


Cette vidéo décrit la structure et fonction des autres organites de la cellule animale : le ribosome, le ribosome, la mitochondrie, le cytosquelette et le centrosome. Le quiz sur le contenu de cette vidéo est disponible au lien suivant : 🤍 Excusez l'erreur de narration à l'instant 2 min 56 : la respiration cellulaire peut produire jusqu'à 38 ATP, (pas 36). Le texte écrit est correct, mais pas la voix. En réalité, 2 sont produits dans la première étape (la glycolyse) qui a lieu dans le cytoplasme, ensuite 36 peuvent être produits dans la mitochondrie (lors du cycle de Krebs et la chaîne respiratoire). En pratique cependant, le rendement n'est jamais aussi bon et on estime que 30 à 32 ATP sont effectivement produits par molécule de glucose.
