Uncontrolled cell division which usually leads to tumors and disease is called:
Metaphase
Cytokinesis
Cancer
Diabetes
Why would it be important to replicate DNA before a cell divides in mitosis?
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.
