E) All of the above are functions of DNA in a cell.

Question

Quizplus · Accepted Answer

DNA has multiple functions in a cell. It stores genetic information in the form of nucleotide sequences, which is passed on from one generation to another. During the cell cycle, DNA is duplicated (replicated), ensuring that each daughter cell receives a complete copy of the genetic material. The DNA sequence also controls the activity of the cell by regulating gene expression- the process by which the genes are turned on or off in response to internal and external signals. DNA can undergo mutations, which can lead to changes in the genetic information content of the cell, potentially affecting the structure and function of its proteins.
