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? atgat tagta cgtcg gcagc tacta atcat

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 the given sequence TACT A:

• T pairs with A.
• A pairs with T.
• C pairs with G.
• T pairs with A.
• A pairs with T.

Answer:

ATGAT
