Summary Introduction
Introduction: Cell division is a natural process in which a parent cell divides to produce two daughter cells. Cell cycle is divided into interphase and mitosis. Interphase is divided into gap1 (G1) phase, synthetic phase (S-phase), and gap 2 (G2) phase. Mitosis phase is divided into prophase, metaphase, anaphase, and telophase.

What is the purpose of mitosis?
a
It ensures that new nuclei have an exact copy of DNA.
b
It ensures the reproduction of mitochondria and chloroplasts.
c
It guarantees that each daughter cell has half the amount of DNA of parent cells.
d
It prevents the occurrence of cancer cells.
Name the phases of the cell cycle. b) During which phases are the chromosomes and then the cytoplasm split, respectively? c) Describe one mechanism that is used to regulate the cell cycle.
Which describes a role for the kinetochore microtubules during mitosis?
Polymerization drives anaphase A.
Depolymerization drives anaphase B.
Depolymerization drives anaphase A.
Depolymerization drives separation of centrosomes (spindle poles) during prometaphase.
