Question

1. in dna, adenine bonds with ______________________ using (#) hydrogen bonds; guanine bonds with ________________ using __ (#) hydrogen bonds.

Explanation:

In DNA, base - pairing rules are based on hydrogen bonding. Adenine (A) pairs with thymine (T) and they form 2 hydrogen bonds. Guanine (G) pairs with cytosine (C) and they form 3 hydrogen bonds. This is a fundamental concept in molecular biology related to the structure of DNA.

Answer:

adenine bonds with thymine using 2 hydrogen bonds; guanine bonds with cytosine using 3 hydrogen bonds.
