Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Each triplet of nucleotides in mRNA that specifies a particular amino acid is called-
A
a codon
B
an anitcodon
C
an intron
D
an exon
Explanation: 

Detailed explanation-1: -Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble-in order-the chain of amino acids that form a protein.

Detailed explanation-2: -Codon*-A codon is the sequence of three consecutive nucleotides that occurs in mRNA which directs the incorporation of a specific amino acid into a protein or represents the starting or termination signals of protein synthesis.

Detailed explanation-3: -(C) A sequence of three nucleotides on mRNA is referred to as a codon and encodes for one amino acid.
