Unit 5: The Central Dogma - The Cell Cycle

Question 1

G0

Answer 1

This is a resting phase that some cells enter when the conditions for cell division are not favorable.

Question 2

G1

Answer 2

This is the first growth phase. The cell increases in size and synthesizes new organelles, e.g. mitochondria.

Question 3

S

Answer 3

This is known as the synthesis phase. The cell’s DNA is replicated, so there are two copies of it, ready for cell division.

Question 4

G2

Answer 4

This is the second growth phase. The cell continues to grow and produce proteins needed for cell division.

Question 5

M phase (mitosis)

Answer 5

The two copies of DNA are separated and the cell then splits into two by dividing the cytoplasm.

Question 6

Which phase is not necessary in all cells?

Answer 6

G0

Question 7

What are the 3 phases of interphase?

Answer 7

G1, S, and G2.

Question 8

What are the phases of mitosis?

Answer 8

PMAT (prophase, metaphase, anaphase, and telophase)

Question 9

Interphase

Answer 9

DNA synthesis, cell growth (everyday functions of the cell)

Question 10

Prophase

Answer 10

-Chromatin winds into chromosomes
-Nucleus dissolves
-Centrioles move to opposite poles
-Spindles attach to centromere
