Question

For deoxyribonucleic acid (DNA) to be replicated, its double helix must first be __________.

zipped closed

transported to the cytosol

broken into two strands

condensed tightly around proteins

Answer 1

For deoxyribonucleic acid (DNA) to be replicated, its double helix must first be **broken into two strands**. This process is known as unwinding or melting, which allows the base pairs to separate so that each strand can serve as a template for the synthesis of new complementary strands.
