Question

hydrogen bonds form between certain nitrogenous bases according to the rules of complementary base pairing. biologists often refer to the nucleotides in dna by the first letters of their base names: a, t, c, and g. according to the rules of complementary base pairing, which sequence of nucleotides would form hydrogen bonds with the dna sequence cagtc? ctgac actga gactg tgact gtcag cagtc

Explanation:

Step1: Recall base - pairing rules

In DNA, adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G).

Step2: Find the complementary sequence for CAGTC

For C, the complementary base is G; for A, it is T; for G, it is C; for T, it is A; for C, it is G. So the complementary sequence is GTCAG.

Answer:

GTCAG
