Mitosis

Question 1

What are the 5 steps of mitosis?

Answer 1

P.P.M.A.T
1. Prophase
2. Prometaphase
3. Metaphase
4. Anaphase
5. Telophase

Question 2

What happens in prophase of mitosis?

Answer 2

• the spindle starts developing
• chromosomes condense by condensins that bind to the DNA
• two chromatids comprise each chromosome
• the mitotic spindle forms

Question 3

What happens in Prometaphase of mitosis.

Answer 3

• The nuclear membrane disintegrates
• spindle microtubules attach to kinetochore at the centromere of the chromatid pair

Question 4

What happens in metaphase of mitosis?

Answer 4

• The chromosomes line up on the metaphase plate (center of cell)

Question 5

What happens in anaphase of mitosis?

Answer 5

• sister chromatids separate
• move towards opposite poles and become individual chromosomes

Question 6

What happens in telophase of mitosis?

Answer 6

• chromosomes arrive at spindle poles
• the nuclear membrane re-forms and the chromosomes relax

Question 7

What are the products of mitosis?

Answer 7

• Two cells that are genetically identical to each other
• each new cell contains 1/2 the cytoplasm and organelle content of the original parent cell
• 2n
