10 A sequence of three nucleotide bases that complements mRNA is known as a (n) -

A Codon

B Anticodon

C Triplet

D Enzyme

The correct option is B) Anticodon

Explanation:

An anticodon can be described as a three nucleotide sequence which is complementary to the mRNA. Based on the anti codons, amino acids are formed which join by polypeptide bonds to form proteins. Hence, option B is correct.

Option A is not correct because a codon is a sequence of three nucleotides which is complementary to the DNA bases. The codon will make up the prescribed mRNA.
