Explanation:
Detailed explanation-1: -Segments of DNA that carry genetic information are called genes, and they are inherited by offspring from their parents during reproduction.
Detailed explanation-2: -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.
Detailed explanation-3: -DNA molecules allow this information to be passed from one generation to the next. DNA is made up of a double-stranded helix held together by weak hydrogen bonds between purine-pyrimidine nucleotide base pairs: adenine (A) paired with thymine (T), and guanine (G) paired with cytosine (C).
