A parent cell divides to form two genetically identical daughter cells in the process of mitosis. For mitosis to take place
A) the parent cell must reproduce its DNA during telophase.
B) the parent cell must replicate its entire genome prior to mitosis.
C) the parent cell must first be fertilized.
D) the parent cell must divide its DNA in half so each daughter cell gets only the genes needed to carry out its functions. In this way, differentiation occurs.

Question

Quizplus · Accepted Answer

Prior to mitosis, the parent cell undergoes DNA replication to ensure that each daughter cell receives a complete and identical copy of its genome. This allows for the production of genetically identical daughter cells in the process of mitosis. Choices A, C, and D are incorrect as they do not accurately describe the process of mitosis.
