Question

The amount of DNA in a mammalian cell in early prophase I is x. What is the amount of DNA in the same cell in anaphase I of meiosis?

• A. $\frac{x}{4}$
• B. $\frac{x}{2}$
• C. x
• D. 2x

Answer 1

Answer: (C)

x

Answer 2

At prophase I, DNA replication has already occurred, and the original amount of DNA has been doubled to x. At anaphase I, the amount of DNA in the cell remains the same because no cytokinesis has occurred yet to separate the cytoplasm.
