Which molecule family is primarily responsible for heredity?

Explanation:
Hereditary information is stored and passed on by the genetic material. The molecule family that carries this information is nucleic acids, primarily DNA. The sequence of nucleotides in DNA encodes genes and can be accurately replicated, enabling traits to be transmitted from parents to offspring. RNA also has roles in gene expression and regulation, and some viruses use RNA as their genetic material, but the stable, heritable storage of genetic information in most organisms is DNA. The other macromolecule families—proteins, carbohydrates, and lipids—perform structural, catalytic, energy, or membrane-related functions, but they do not serve as the main repository for hereditary information.
