How are amino acids transfered to the ribosome into a growing polypeptide chain?

∙ 11y ago
The ribosome uses tRNA that matches the current codon (triplet) on the mRNA to append an amino acid to the polypeptide chain. This is done for each triplet on the mRNA, while the ribosome moves towards the 3' end of the mRNA.

What is the purpose of a transfer RNA?
To carry the next amino acid to be added to a growing polypeptide chain during translation process that takes place in the ribosomes.
A long chain of amino acids?
polypeptides - The Dude That is Friends with THE DUDE
What is the result of the translation process?
An amino acid chain
What do you call the covalent bond that hold amino acids together?
Polypeptide bonds
A chain of amino acids forms what?
A chain of amino acids form a polypeptide chain. Once the polypeptide chain goes under a seris of folds, due to side chain reactions it becomes a functional protien.
Amino acids are transferred to the ribosome to be incorporated into a growing polypeptide chain by?
tRNA
When is the polypeptide (protein) released from the ribosome?
Polypeptides are proteins, just they are short. For example, Insulin is a protein of just 56 amino-acids; it could be considered to be a very large polypeptide.
What is tRNA's function?
tRNAs are small RNA molecules that carry amino acids to growing polypeptide chains that are being made in a ribosome. The have anti-codons that are complimentary to the codons on the mRNA. They carry an amino acid that is specific to their anti-codon.
The step of translation in which amino acids are added one at a time to the growing polypeptide is?
elongation
What dictates the corresponding sequence of amino acids in a growing polypeptide chain?
The sequence of amino acids being added to the growing polypeptide chain is controlled by the instructions (codons, 3-base codes) on the mRNA. These are a copy of the coding regions of the gene from the DNA in the nucleus.
What happens at the end of translation in the p site?
the amino acids detach from the ribosome
Observe how the mRNA interacts with the ribosome in the simulation. How is this interaction similar to what actually happens in translation?
The interaction between mRNA and ribosomes in the simulation is meant to reflect the process of translation that occurs in cells. During translation, the ribosome uses the information stored in the mRNA molecule to synthesize a protein. The ribosome moves along the mRNA molecule and reads its codons (sets of three nucleotides) to determine which amino acids should be added to the growing polypeptide chain. In the simulation, the mRNA molecule is represented as a linear sequence of codons, and the ribosome is represented as a moving object that recognizes and interacts with the codons. The ribosome moves along the mRNA and recognizes each codon by binding to it. This interaction is similar to what happens in real cells, where the ribosome recognizes codons by binding to specific sites on the mRNA molecule. In the simulation, the ribosome can also interact with tRNA molecules, which bring the correct amino acids to the ribosome for incorporation into the growing polypeptide chain. This is similar to what happens in real cells, where tRNA molecules bring the correct amino acids to the ribosome for use in protein synthesis. Overall, the interaction between mRNA and ribosomes in the simulation is meant to closely resemble the process of translation that occurs in cells.
What is a ribosome and what does it do?
A ribosome is a two subunit complex made of protein and catalytic RNA that unites as one unit when mRNA docks on the large subunit. Ribosomes are the " workbench " on which proteins are synthesized. The ribosome crawls along the mRNA and knits together a polypeptide chain from the free amino acids brought to the ribosome by tRNA.
What r two basic steps of polypeptide synthesis?
The 2 basic steps of polypeptide synthesis are:Transcription - the synthesis of mRNA from a DNA template. Only one strand of DNA is copied, and a single gene may be transcribed thousands of times.Translation - the process where ribosomes synthesize proteins using the mature mRNA transcript produced during transcription. The ribosome attaches to mRNA, and then moves along the mRNA adding amino acids to the growing polypeptide chain.
What is used during RNA translation.?
mRNA- a transcript of DNA which serves as instuctions for polypeptide formation. amino acid- a single buildin block of protein. tRNA- a molecule that carries a specific amino acid and recognizes its complementary base sequence on an mRNA strand. ribosome- an organelle which serves as the "factory" where amino acids are addes to a growing polypeptide chain.
Are Transcription and translationprocesses of protein synthesis?
Yes.Transcription is the transferring of the genetic code from DNA to mRNA.Translation is the threading of this mRNA through a ribosome where it is read and individual amino acids are brought to the ribosome to synthesize a polypeptide chain. A nascent protein.A simplified answer.
