Mitosis

Question 1

Anaphase

Answer 1

• Separase enzyme splits the proteins that hold together the sister chromatids
• daughter chromosomes are pulled to opposite sides

Question 2

Prometaphase

Answer 2

-nuclear envelope breaks, freeing the chromosomes from the nucleus
- centrosomes reach opposite poles
Chromosomes finish condensing

Question 3

Prophase

Answer 3

• Chromatin begins to condense

- centrosomes move to opposite sides

Question 4

Telophase

Answer 4

• DNA unwinds and a new nuclear membrane forms

- any remaining spindle microtubules are depolymerized

Question 5

Cytokinesis

Answer 5

• Splitting of the cytoplasm
• microfilaments pinches two daughter cells like a belt
• cleavage is formed by myosin and actin

Question 6

Interphase(G2)

Answer 6

• Occurs before mitosis
• DNA replicates
• cell makes a second centrosome

Question 7

Metaphase

Answer 7

• Chromosomes line up in the middle of the cell (equator)

- confirms that there is a microtubule attached to every kinetochore
