A parent cell divides to form two genetically identical daughter cells in the nuclear process of
mitosis. For mitosis to take place
a. the parent cell must first be fertilized.
b. the parent cell must replicate all its chromosomes prior to mitosis
c. the parent cell must replicate its DNA during telophase
d. the parent cell must divide its DNA in half so that each daughter cells
