~Spindle fibres attach to the centromere.

Question 4

Anaphase

Answer 4

Chromosomes are pulled to either side of the cell to form two new cells.

Question 5

Telophase

Answer 5

~Chromosomes lose their shape and stretch out.

~New nuclear membrane forms.

Question 6

Cytokinesis

Answer 6

~Cell membrane forms to divide the new cells.
~Begins around the same time as telophase.
~After cytokinesis human cells have 46 chromosomes.
