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 tacta? tacta atcat atgat gcagc cgtcg tagta

Explanation:

Step1: Recall base - pairing rules

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

Step2: Find complementary sequence for TACTA

For T in the given sequence, the complementary base is A; for A, it is T; for C, it is G; for T, it is A; for A, it is T. So the complementary sequence of TACTA is ATGAT.

Answer:

ATGAT
