Question

A body cell has made a copy of its genetic material and is growing and storing energy in preparation for cell division. Which of the following is the best conclusion you can make about the life cycle of this cell?

A. The cell is in prophase and will enter metaphase next.
B. The cell is in the G2 phase of interphase and will enter prophase next.
C. The cell will make a second copy of its DNA next in order to undergo meiosis.
D. The cell will separate into two daughter cells next, and then cytokinesis will occur.

I think the answer is B but im just not sure, can someone help me please!!??

Answer 1

You know that it's a body cell so that means it is preparing for a particular kind of cell division -- Mitosis.
What does the cell cycle look like?
Mitosis (PMAT- Prophase, Metaphase, Anaphase, Telophase) >>> Growth 1 (G1- organellles reproduce so they can be distributed to the two future daughter cells) >>> Synthesis (S phase - DNA is replicated so that there will be enough for both daughter cells to have a complete set of genes) >>> G2 (More organelles reproducing and storing energy as in G1) >>> repeats the whole cyle over again.

Mitosis > G1 > S > G2 > repeat

So, where are we? Right after S phase, since DNA was synthesized and we're preparing to begin cell division, which is what Mitosis is. Prophase is the first phase of Mitosis, so your answer B was correct!

Keep in mind the differences between G1 and G2 differ between what cells and organisms you're talking about, and is probably not important to the course you're currently taking!
