Chapter II: Mitosis

Question 0

Metaphase

Answer 0

• Chromosomes align in the equatorial plane/metaphase plate

- Spindle fibers attaches to chromosomes

Question 1

Prophase

Answer 1

• Chromosomes condense and coil up
• Centrioles divide and move apart, establishing opposite poles, and then forms spindle fibers
• Dissolution of the nuclear membrane occurs

Question 2

Anaphase

Answer 2

-Late replication of centromeres occur, and they split, reeling in daughter chromosomes causing migration to opposite poles

Question 3

Telophase

Answer 3

• Daughter chromosomes arrive at the poles
• Chromosomes decondense
• Nuclear membrane reforms
• Cytokinesis commences

Question 4

Mitosis v. Meiosis

Answer 4

Mitosis - homologs align independently
- promotes genetic continuity
Meiosis - homologs forms in pairs (synapsis)
- promotes genetic variability
