Around 9 hours

Question 4

Describe G2

Answer 4

DNA present as 2 identical sister chromatids

Question 5

What is interphase

Answer 5

The time between Mitosis

G1,S,G2

Question 6

Name the phases of mitosis

Answer 6

Prophase
Metaphase
Anaphase
Telophase

Question 7

What happens in prophase?

Answer 7

DNA condenses into chromosomes, each containing two sister chromatids.

Question 8

Whats happens in metaphase?

Answer 8

Chromosomes align on the central plane of the spindle, and microtubule spindle fibres join to the centromeres.
Nuclear membranes disintegrate.

Question 9

What happens in Anaphase?

Answer 9

The sister chromatids are separated and pulled to the spindle poles.

Question 10

What happens in telophase?

Answer 10

The chromatids are pulled to each pole
The nuclear envelope begins to reform
The genetic material begins to decondense.
