Question

how does the anticodon on trna and codon on mrna bind to each other?
complementary base pairing
nuclear bonds
ionic bonds

Explanation:

In molecular biology (a subfield of Biology, which is part of Natural Science), the binding between the anticodon of tRNA and the codon of mRNA occurs via complementary base pairing. This is a fundamental principle in nucleic acid interactions, where adenine (A) pairs with uracil (U) (in RNA) and cytosine (C) pairs with guanine (G). Nuclear bonds are not related to this molecular interaction, and ionic bonds are not the primary mechanism here.

Answer:

A. complementary base pairing
