Start Codon Methionine's code is AUG which is also a start codon causing initiation of translation.
What else can I help you with?
What amino acid does every newly translated protein begin with?
In eukaryotes, every newly-translated protein begins with the amino acid methionine (Met, M). This is because the start codon that signals the beginning of translation is AUG, which is also the codon for methionine - so the correlation is obligatory. The methionine may be removed during post-translational processing/modification.In prokaryotes, however, every newly-translated protein begins with formylmethionine (fMet), a methionine derivative with a formyl group added to the amino group. This difference can be used as a target for antibiotic therapy. As with methionine, the formylmethionine can be removed after translation.
What is the first codon in every mRNA?
AUG, which codes for the amino acid methionine.
What polypeptide would you expect from a poly-G mRNA that is 30 nucleotides long?
A poly-G mRNA that is 30 nucleotides long would result in a polypeptide consisting solely of glycine amino acids. This is because each codon codes for a specific amino acid, and in this case, every codon (GGG) codes for glycine.
How many nucleotides are necessary to code for a polypeptide that is 200 amino acids long?
A minimum of 600 nucleotides is necessary to code for a polypeptide that is 200 amino acids long because each amino acid is coded for by a sequence of three nucleotides in mRNA. This is due to the genetic code being triplet, where every three nucleotides represent one amino acid.
What is codon recognition?
Codon recognition is the specific pairing of three nucleotides in mRNA with complementary anticodons in tRNA during protein synthesis. This process ensures that the correct amino acid is added to the growing polypeptide chain according to the genetic code. Misrecognition of codons can lead to errors in translation and produce abnormal or nonfunctional proteins.
How many amino acids will be in the first amino acid in every growing polypeptide?
The first amino acid in a growing polypeptide chain is usually methionine when translation initiates in eukaryotes, and formylmethionine in prokaryotes. Therefore, there will be one amino acid in the first position of every growing polypeptide chain.

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.
There can only be one what for every codon?
There can only be one amino acid for every codon. Tryptophan and Methionine are the types of amino acids that correspond to codon.
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.
What is the first codon in every mRNA?
AUG, which codes for the amino acid methionine.

What is the amino acid that all proteins start with?
In chemistry, an amino acid is a molecule containing both amine and carboxyl functional groups. These molecules are particularly important in biochemistry, where this term refers to alpha-amino acids with the general formula H2NCHRCOOH, where R is an organic substituent Amino acids are critical to life, and have a variety of roles in metabolism. One particularly important function is as the building blocks of proteins, which are linear chains of amino acids. http://en.wikipedia.org/wiki/Amino_acid === === The answerer to this question did not actually answer it. The question is asking what amino acid do all proteins start with, not for the definition of an amino acid. The answer is methionine, because the gene for every protein has a start codon in the mRNA of AUG, and AUG codes for the amino acid methionine.
How many nucleotides are necessary to code for a polypeptide that is 200 amino acids long?

What codon must every mRNA begin with?
They all begin with AUG, which is the start codon.
What contains amino acids?
Every living thing contains amino acids. Amino acids are the building blocks of DNA.
