A codon consists of the bases Adenine, Guanine, and Cytosine in that order. Which amino acid would that code for?
|
|
Cysteine
|
|
|
Phenylalanine
|
|
|
Serine
|
|
|
Tryptophan

Explanation:
Detailed explanation-1: -Serine is the only amino acid that is encoded by two disjoint codon sets (TCN & AGY) so that a tandem substitution of two nucleotides is required to switch between the two sets. We show that these codon sets underlie distinct substitution patterns at positions subject to purifying and diversifying selections.
Detailed explanation-2: -Among the 20 amino acids, three of them-leucine (Leu), arginine (Arg), and serine (Ser)-are encoded by six different codons. In comparison, all of the other 17 amino acids are encoded by either 4, 3, 2, or 1 codon.
Detailed explanation-3: -As shown in the figure, the the codon of serine is AGU. Therefore, the coding sequence of DNA is AGT.
