C AND G TEST 3 EXAM

Question 1

Prophase (MITOSIS)

Answer 1

• DNA= Chromosomes form, each joined to sister chromatid
• Nucleoli disappear, nuclear envelope phosphorylated
• Mitotic spindles form
• Centrosomes move away from each other

Question 2

Prometaphase (MITOSIS)

Answer 2

• Nuclear envelope completely fragments
• Microtubules attach to the kinetochore of chromatids
• Chromosomes begin moving toward the middle of the cell
• Non-Kinectore microtubules lengthen the cell
  -DNA= sister chromatids fused

Question 3

Metaphase (MITOSIS)

Answer 3

• Chromosomes all arrive at metaphase plate
• DNA = sister chromatids fused
• M checkpoint: All chromosomes attached to microtubules

Question 4

Anaphase (MITOSIS)

Answer 4

• Sister chromatids are pulled apart from each other
• DNA = Chromosomes, no sister chromatids

Question 5

Telophase (MITOSIS)

Answer 5

• Two nuclei begin to form
• Nucleoli reappear
• Mitotic spindle breaks down
