Quizplus · Accepted Answer

Genes are the units of heredity that maintain their structural identity from one generation to another, meaning they carry the genetic information that is transmitted from parents to offspring. Enzymes are proteins that catalyze chemical reactions, but they are not units of heredity. Mutations are changes in the genetic material that can alter the sequence of DNA, but they do not maintain structural identity. Nucleic acids such as DNA and RNA are involved in the storage and transmission of genetic information, but they are not themselves the units of heredity.
