"Craft your masterpiece by chiseling away, bit by bit, with the sculptor's patience of daily discipline."

A scientist is looking to study mouse cells in various stages of mitosis. He obtains a culture of cells and treats them with a chemical that arrests the cells during DNA replication.
What is the most likely result of the experiment?
|
A
|
|
He will successfully have arrested the cells in various stages of mitosis for observation.
|
|
|
B
|
|
The cells will complete mitosis and be arrested during the S phase of interphase.
|
|
|
|
C
|
|
The cells will complete mitosis and will be arrested upon entry into G1.
|
|
|
|
D
|
|
The cells will be unaffected by the chemical entirely.

"I got a 120 on my first CARS practice test, and I amost immediately thought that I would have to postpone my MCAT. I finished the Testing Solutiosn
bootcamp, and I ended up scoring 129 on the actual MCAT! I definitely credit Testing Solutions."

DNA replication in the eukaryotic cell cycle happens only during S phase. Mitosis involves only nuclear division, not DNA replication. Therefore mitosis would be unaffected by the
chemical and the cells would complete mitosis and would only be arrested once they entered S phase, making (B) the correct answer.
