Explanation:
Detailed explanation-1: -Complementary Sequence: Since DNA has two strands, every DNA sequence has a complementary sequence running parallel. In the complementary sequence, Adenine (A) is always paired with Thymine (T), and Cytosine (C) is always paired with Guanine (G).
Detailed explanation-2: -The bases are paired by This is called complementary base pairs. Thus one strand of DNA is complementary to the other strand (opposite/matching). 15. Adenine and Guanine.
Detailed explanation-3: -mRNA → DNA For converting a sequence from mRNA to the original DNA code, apply the rules of complementary base pairing: Cytosine (C) is replaced with Guanine (G) – and vice versa. Uracil (U) is replaced by Adenine (A)
