Question

Quizplus · Accepted Answer

DNA is the blueprint for all living organisms that guides their growth, development, behavior, and reproduction.

Answer: D
 Viruses are classified as nonliving because they lack the ability to reproduce on their own and do not have DNA or RNA. However, some viruses do have genetic material in the form of DNA or RNA.

A) and B) are incorrect statements. DNA does not form the protective outer membrane of cells (that is the cell membrane), and it is not found only in eggs and sperm but is present in all cells of an organism.
