Why do all polypeptide chains start with methionine?
Because the nucleotide that codes for methionine also is the "start" signal, so whenever a polypeptide starts it uses the exact same code (AUG) so methionine must start every polypeptide chain.
What is the codon for methionine is AUG what is its anticodon?
The anticodon for methionine is UAC. It pairs with the methionine codon AUG during protein synthesis.
Is methionine the same compound as methianine?
No, methionine and methianine are not the same compound. It is possible that "methianine" is a misspelling or a different term for methionine. Methionine is an essential amino acid that is found in proteins, while "methianine" does not have a recognized meaning or chemical structure.
What amino acid has AUG?
METHIONINE
Do all proteins start with methionine?
Proteins have undergone post-transcriptional modifications, thus may not start with methionine after it has been modified.
What is the three-letter code for the amino acid methionine and how does it contribute to protein synthesis?
The three-letter code for the amino acid methionine is Met. Methionine is important in protein synthesis as it serves as the starting point for protein production and helps initiate the process of building new proteins in the body.
What is the start codon and what amino acid does it code for?
AUG. The amino acid methionine. Bases read; adenine-uracil-guanine
Why do all polypeptide chains start with methionine?
Because the nucleotide that codes for methionine also is the "start" signal, so whenever a polypeptide starts it uses the exact same code (AUG) so methionine must start every 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 is the codon for methionine is AUG what is its anticodon?
The anticodon for methionine is UAC. It pairs with the methionine codon AUG during protein synthesis.
Which amino acid begins every protein chain?
Methionine is typically the amino acid that initiates the synthesis of most proteins in cells. It serves as the start codon in the genetic code, signaling the beginning of protein translation.
For which specific amino acid does each codon code in the genetic code?
Each codon in the genetic code codes for a specific amino acid. For example, the codon "AUG" codes for the amino acid methionine.
What is anticodon for methinonine?
The anticodon for methionine is 5'-CAU-3'. When the methionine tRNA binds to a methionine codon (AUG) on a mRNA strand, the anticodon pairs with the codon through complementary base pairing, allowing for the insertion of methionine during protein synthesis.
When a protein is synthesized what amino acid is always the first amino acid that is positioned during any protein synthesis?
"AUG" actually corresponds to a region of code on mRNA and is NOT an amino acid. The tRNA that has the anticodon 5' CAU 3' and recognizes AUG is a tRNA charged with Methionine. Therefore, methionine is the first amino acid incorporated into a growing polypeptide. Note this is true for only eukaryotes, prokaryotes have N-formyl methionine as their first amino acid.
What amino acid is encoded by the initiation codon AUG?
The amino acid that is encoded by the initiation codon AUG is methionine. It is the only amino acid which is specified by just one codon.
What does cyanogen bromide cleave?
Cyanogen bromide cleaves at methionine residues in proteins, specifically at the carboxyl side of methionine. It reacts with the sulfur atom of methionine, resulting in the cleavage of the peptide bond and the formation of homoserine lactone and a truncated peptide.
Is methionine the same compound as methianine?
No, methionine and methianine are not the same compound. It is possible that "methianine" is a misspelling or a different term for methionine. Methionine is an essential amino acid that is found in proteins, while "methianine" does not have a recognized meaning or chemical structure.
