3 3.7 Mitosis

Question 1

What are the individual strands on a chromosome called

Answer 1

Chromatids

Question 2

What holds chromatids together in chromosomes

Answer 2

Centromere

Question 3

What is the order of mitosis

Answer 3

Prophase, Metaphase, Anaphase, Telophase

Question 4

What happens in the Prophase

Answer 4

Centrioles for a network of protein fibres (spindle fibres)
Chromosomes condense
The nuclear envelope + Nucleolus breaks down

Question 5

What happens in the Metaphase

Answer 5

Chromosomes align along the spindle fibers
Nucleus completely breaks down

Question 6

What happens in the Anaphase

Answer 6

Centromeres divide which split chromosomes as their pulled to a centriole at different poles of the cell

Question 7

What happens in the Telophase

Answer 7

The cell begins to split and in each cell the chromosomes are enveloped in the nuclear envelope again, cytokinesis also begins (division of cytoplasm)
