Mitosis

Question 1

S phase

Answer 1

Replicate during S phase (interphase)

Question 2

Prophase

Answer 2

Centrosome move to opposite ends of the nuclear envelope

Question 3

Late Prophase

Answer 3

Kinetochores develop on each chromatid

Question 4

Prometaphase

Answer 4

Nuclear envelope breaks down and the spindle forms

Question 5

Metaphase

Answer 5

-The chromosomes line up at the metaphase plate (center)
-A spindle assembly checkpoint occurs at the end (if good activates APC and goes towards anaphase)

Question 6

Anaphase

Answer 6

-Separation of chromatids controlled by M phase cyclin-CDK
-“Check point” → activates anaphase-promoting complex

Question 7

Telophase

Answer 7

the chromosomes reach opposite poles of the cell, a nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense back into chromatin.

Question 8

Cytokinesis

Answer 8

Division of the cytoplasm

Question 9

Cytokinesis In animal cells

Answer 9

-Cell membrane pinches in between the nuclei
-Contractile ring of microfilaments of actin and myosin forms
-Interact to contract and pinch cell in two

Question 10

Cytokinesis In plant cells

Answer 10

-Vesicle from the golgi apparatus appear along the plane of cell division
-These fuse to form a new cell membrane
-Content of vesicles form a cell plate
-Beginning of the new cell wall
