the first phase of interphase is?
o g2
o go
o s
o g1

question 8
10 pts
when cells leave the cell cycle, they exit during g1 phase and then enter g0 phase, a resting period. most
normal cells can leave g0 phase and reenter the cell cycle at g1 phase before entering s phase. cancer
cells are different because they cannot enter g0 phase and are likely to do which of the following?
o repeat the cell cycle continuously
o die after completing mitosis
o mutate during g1 phase
o fail to complete s phase

Explanation:

Question 7:

• Interphase has three phases: G1 (first gap), S (synthesis), and G2 (second gap). So the first phase is G1.

Question 8:

• Since cancer cells cannot enter the resting G0 phase, they keep cycling. Normal cells can rest in G0, but cancer cells lack this control and continuously repeat the cell cycle.

Answer:

Question 7: D. G1
Question 8: A. Repeat the cell cycle continuously
