Module 2 - Cell Division (mitosis)

Question 1

what are the stages of mitosis?

Answer 1

prophase
metaphase
anaphase
telophase
(cytokinisis)

Question 2

what is the overall process of mitosis?

Answer 2

process od cellular division that results in the production of 2 genetically identical daughter cells

46 chromosomes

Question 3

summarise prophase:

Answer 3

• nuclear envelope breaks down
• nucleolus breaks down
• centrosomes move to the center of the cell, forming poles

Question 4

summarise metaphase:

Answer 4

• each chromosome reaches the pole
• centrosomes form spindle fibres
• chromosomes line up on equator attatched by spindles to centromere

Question 5

summarise anaphase:

Answer 5

• chromosomes split at centomere
• chromatids move to opposite poles (centromere first)
• chromatids are pulled appart

Question 6

summarise telophase:

Answer 6

• nucleolus reforms
• nuclear envelope reforms
• spindle fibres break down
• chromatids decondense
• cytokinisis (division of cytoplasm by constriction)
