What is the fundamental difference between mitosis and meiosis?
A.
DNA is replicated twice in meiosis, but only once in mitosis.
B.
The number of DNA molecules per cell nucleus is cut in half in meiosis but remains constant in mitosis.
C.
The number of chromosomes doubles in meiosis, whereas it stays the same in mitosis.
D.
