Mitosis Stages

Question 1

Interphase

Answer 1

Stage between nuclear divisions
Chromosomes not visible
As cell leaves interphase, chromatin threads become shorter, thicker & visible

Question 2

Prophase

Answer 2

Chromatin threads condense
Visible as double strands, contains 2 chromatids held together at centromere
Nuclear membrane breaks down

Question 3

Metaphase

Answer 3

Chromosomes move to centre of cell & line up along equator

Question 4

Anaphase

Answer 4

Spindle fibres attach to chromatids, help pull them apart

Chromatids separate at centromere, move to opposite poles of spindle

Question 5

Telophase

Answer 5

Chromosomes de-condense
Chromatin unwinds, becomes less visible
Nucleoli reform
Spindle disassembles
