Week 2 (Mitosis)

Question 1

What happens in Prophase (MITOSIS)?

Answer 1

Chromosomes replicated.
Chromosomes contract, smaller/fatter
Centrioles are at end of each cell
Spindle fibers start to form
nuclear membrane breaks down.

Question 2

What happens in Metaphase (MITOSIS)?

Answer 2

Chromosomes line up at the equator (middle).
Chromatids draw apart from centromere

Question 3

What happens in Anaphase (MITOSIS)?

Answer 3

Chromosomes attach themselves to spindle fibers
Chromatids move apart to opposite poles of the cell

Question 4

What happens in Telophase (MITOSIS)?

Answer 4

Chromatids will be new chromosomes for daughter cells.
Spindle fibers break down
Nuclear membrane reforms itself
Cell constricts (divides into 2)- cytokinesis

Question 5

What happens in Interphase (MITOSIS)?

Answer 5

Rest stage to prepare for replication
DNA makes a copy of itself- ready for prophase
