Flashcards in Mitosis Deck (12):
1

What type of human cells undergo mitosis

Somatic body cells

2

What number of cells does somatic cells have

Diploid 2n

3

What is the first stage prior to mitosis

interphase

4

How long does interphase take

18-24 hours

5

What happens in interphase

Cell begins to grow and prepare to divide. The chromosomes replicate in this stage. cohesion occurs. Centrosomes also duplicate

6

What happens in prophase

Chromosome condensation. Mitotic asters replace interphase microtubules and mitotic aster separation occurs

7

Prometaphase vs metaphase

Prometaphase = chromosomes captured, bi-oriented and travel to the spindle equators. Nuclear envelope bd.
Metaphase = chromosomes allign at metaphase plate

8

Anaphase A

chromosomes move to poles

9

Anaphase B

Spindle pole separation occurs

10

Telophase

Nuclear envelope reassembles, contractile ring forms = cellular separation is now possible

11

Cytokinesis

microtubule array reforms, cleavage furrow from contractile ring.

12

Product

2 daughter cells that are identical to parent cells with respect to genetic information.
