Question 3

G0

Answer 3

cells are resting, not dividing

Question 4

Synthesis (S) Phase

Answer 4

duplicate genome and centrosomes

Question 5

Gap Phase 2 (G2)

Answer 5

last preparations (organelles replicated)
*check for errors in DNA!
*make sure mitogen promoting factor present

Question 6

Prophase (MITOSIS and M2)

Answer 6

-chromatin condenses into chromosomes
-nucleolus and nuclear envelope disappear
-spindle apparatus forms.

Question 7

Metaphase (MITOSIS and M2)

Answer 7

-spindle apparatus guides chromosomes to metaphase plate

Question 8

Anaphase (MITOSIS and M2)

Answer 8

-kinetochore microtubules shorten, pull sister
chromatids apart

Question 9

Telophase (MITOSIS and M2)

Answer 9

-chromosomes segregated, nuclear membranes reform
-chromosomes decondense into chromatin

Crossing over occurs!!! in addition to everything else

Question 11

What makes Meiosis M1 different than Mitosis?

Answer 11

Uses tetrads instead of chromosomes

Question 12

What makes Meiosis A1 different than Mitosis?

Answer 12
