Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A triplet of mRNA is called a
A
codon
B
anticodon
C
amino acid
D
peptide bond
Explanation: 

Detailed explanation-1: -It is a sequence of three nucleotides present in the mRNA, which is commonly called a codon or genetic code. A protein is made up of small units called amino acids that are arranged in sequence inside the protein structure.

Detailed explanation-2: -A codon is the triplet of a set of bases (or nucleotides) in DNA that codes for an amino acid. The triple base complement for a codon is called an anticodon; By convention, triplets in mRNA are called codons, and triplets in tRNA are called anticodons. These codons are translated into protein sequences.

Detailed explanation-3: -The DNA sequence is transcribed to form mRNA, which then is translated into protein by ribosomes. The genetic code consists of 64 triplet RNA codons that specify the 20 amino acids and sites of translation termination (stop codons).
