Cell Cycle/ Mitosis/ Cytokinesis

Question 1

(cell cycle) G1 phase:

Answer 1

Cell grows and produces organelles

Question 2

(cell cycle) S phase:

Answer 2

DNA synthesis (chromosomes are copied)

Question 3

(cell cycle) G2 phase:

Answer 3

Cell grows and produces organelles needed for the M phase

Question 4

(cell cycle) M phase:

Answer 4

Mitosis (nuclear division) and cytokinesis (cell division) occur

Question 5

Define Mitosis:

Answer 5

Division of a cell into 2 identical cells

Question 6

What happens before mitosis?
Define sister chromatids:

Answer 6

-Chromosomes have copied themselves

-Sister chromatids: original chromosome and its exact copy are attached to each other

Question 7

(mitosis) Prophase:

Answer 7

Nuclear membrane falls apart and spindle fibers start to form

Question 8

(mitosis) Metaphase:

Answer 8

Sister chromatids line up along the middle of the spindle fibers

Question 9

(mitosis) Anaphase:

Answer 9

Sister chromatids separate and move to opposite ends of the cell

Question 10

(mitosis) Telophase:

Answer 10

Spindle fibers break down and new nuclear membrane forms around each set of chromosomes

Question 11

Cytokinesis:

Answer 11

Cytokinesis occurs when the cytoplasm divides, forming two new cells
