Why methionine is the first amino acid in every growing polypeptide?
Start Codon Methionine's code is AUG which is also a start codon causing initiation of translation.
What regions of a ribosome holds the growing polypeptide?
The P site
What is the role of tRNA durning translation?
A tRNA molecule brings an amino acid from the cytoplasm to its correct location on the mRNA molecule at the ribosome where it will be added to the amino acid chain. A tRNA molecule has an anticodon that is complimentary to a specific mRNA codon for a particular amino acid.
Assembly of a protein molecule according to the code in a mRNA molecule?
Translation. The ribosome uses the mRNA molecules to assemble amino acids into proteins by matching the triplet codons on mRNA to the anticodons (complementary RNA) on tRNA. These tRNA molecules have the corresponding amino acid attached, which the ribosome (ribozyme) can then use to add to the growing polypeptide chain. The process is highly specific to avoid errors.
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 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.
When does the polypeptide stop growing?
It reaches a stop codon on the mRNA molecule
The step of translation in which amino acids are added one at a time to the growing polypeptide is?
elongation
What is the role of the tRNA anticodon?
the tRNA carries only the amino acid that the anti-codon specifies. for example: one tRNA molecule for the amino acid cysteine has an anticodon of ACA. this anticodon binds to thh mRNA codon UGU.
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.
What is attached to the tRNA molecule?
Transfer RNA is an inverted "L" shaped molecule. Each tRNA recognizes only one specific amino acid, which becomes attached to the 3'-hydroxyl end (the tail or top of the inverted "L") of the molecule. On the opposite end of the molecule are 3 nitrogen bases called an anticodon triplet, which pair up with messenger RNA codons during translation.
What is the type of RNA that is converted to a protein during translation?
Messenger RNA (mRNA) is translated into polypeptides on ribosomes by transfer RNA (tRNA).
What happens to the growing of polypeptide?
It will either continue growing, or develop into a functional protein.
What codons mapped to two different amino acids What would the effect be on your translation of coded messages What would the effect be on the production of proteins?
There is no codon that codifies for two amino acids. The explanation is easy considering that the codon must be recognized by the tRNA that carries a particular amino acid that is going to be coupled into the growing polypeptide chain during translation event. If for any reason there is a codon that codifies for two amino acids it would be an important cause that the translation from mRNA to protein be with multiple errors in amino acid secquence as there is no molecule that discriminates which amino acid should be coupled in the nascent polypeptide chain.
Why methionine is the first amino acid in every growing polypeptide?
Start Codon Methionine's code is AUG which is also a start codon causing initiation of translation.
What places the amino acid on the growing polypeptide chains?
Ribo
What regions of a ribosome holds the growing polypeptide?
The P site
