One set of chromosomes

Question 2

Diploid cell

Answer 2

Two sets of chromosomes

Question 3

Interphase

Answer 3

Phase in the cell cycle when the cell is not dividing

Question 4

Mitosis

Answer 4

One nucleus divides to form two nuclei , each containing the same number of chromosomes with identical genes

Question 5

Prophase

Answer 5

Chromatin starts to contract
Chromosomes become visible
Spindle fibres form

Question 6

Metaphase

Answer 6

Spindle fibres attach to centromere

Chromosomes line up at equator of cell

Question 7

Anaphase

Answer 7

Spindle fibres contract

One strand of each chromosome pulled to opposite sides

Question 8

Telophase

Answer 8

Spindle fibres break down
Nucleoli re-form
Original nucleus has divided into 2 identical nuclei
