why AUG where be a start codon
1 answer
The AUG codon serves as the start codon in most organisms. Start codons are specific sequences of three nucleotides (in this case, Adenine-Uracil-Guanine or AUG) that indicate the beginning of a protein-coding sequence in mRNA. The AUG codon also codes for the amino acid Methionine, which is often the first amino acid incorporated into a growing polypeptide chain during translation. Additionally, cellular machinery recognizes and binds to the AUG codon to initiate the process of protein synthesis.
