The phase where the cell membrane moves inward to create two daughter cells with their own nucleus and identical chromosomes is known as....

• prophase

• intephase

• metaphase

• cytokinesis

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

• In order for genetic information to be transferred into daughter cells.

• In order for the cell to be able to increase in size.

• In order for the DNA to be contained in the nucleus.

• In order for the cell to re-order the DNA sequencing in the new cells.
