Question

. DNA is double stranded due to interactions between adenine, cytosine, guanine, and thymine, which are

Answer 1

Adenine of one DNA starnd binds with thymine of another DNA strand by means of a double hydrogen bond (A=T).

Guanine of one DNA strand binds with cytosine of another DNA strand by means of a triple hydrogen bond .
