Mitosis

Question 1

Purpose of mitosis

Answer 1

Single cell Division which produces 2 genetically identical Daughter cells

Question 2

Process of mitosis

Answer 2

1. Interphase
2. Prophase
3. Metaphase
4. Anaphase e
5. Telophase
6. Cytokinesis

Question 3

Interphase

Answer 3

• DNA duplicates (2N -> 4n)
  Everything duplicates

Question 4

Prophase

Answer 4

The chromatin condensed into visible chromosomes, each consisting of two sister cromatids.

The nuclear membrane begins to break down

The centrioles move to opposite ends and form spindle fibres

Question 5

Metaphase

Answer 5

• spindle fibres attach to the chromosomes
• spindle fibres align chromosomes along the middle

Metaphase (Middle)

Question 6

Anaphase

Answer 6

• Spindle fibres pull apart the chromosomes
• pull the single stranded chromosomes to opposite ends

Anaphase = Away

Question 7

Telophase

Answer 7

Chromosomes uncoil to form chromatin
- spindle fibres disappear
- nuclear membrane reforms
- cell pinches in the middle to seperate cytoplasm, forming cleavage

Question 8

Cytokinesis

Answer 8

Cell split to produce 2 genetically identical diploid daughter cells
