Mitosis

Question 1

What type of human cells undergo mitosis

Answer 1

Somatic body cells

Question 2

What number of cells does somatic cells have

Answer 2

Diploid 2n

Question 3

What is the first stage prior to mitosis

Answer 3

interphase

Question 4

How long does interphase take

Answer 4

18-24 hours

Question 5

What happens in interphase

Answer 5

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

Question 6

What happens in prophase

Answer 6

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

Question 7

Prometaphase vs metaphase

Answer 7

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

Question 8

Anaphase A

Answer 8

chromosomes move to poles

Question 9

Anaphase B

Answer 9

Spindle pole separation occurs

Question 10

Telophase

Answer 10

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

Question 11

Cytokinesis

Answer 11

microtubule array reforms, cleavage furrow from contractile ring.

Question 12

Product

Answer 12

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