What is the structure of a DNA molecule, and how is it duplicated?

1 answer:

3 0

Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs. Duplication of the genetic information occurs by the use of one DNA strand as a template for formation of a complementary strand. (There’s a picture below of a DNA strand )
