During Interphase of the Cell Cycle, ________

Question

During interphase of the cell cycle, ________.
A) DNA recombines
B) sister chromatids move to opposite poles
C) the nuclear membrane disappears
D) RNA replicates
E) DNA content essentially doubles

Accepted Answer

During interphase, the cell engages in DNA replication, resulting in a doubling of the DNA content. This prepares the cell for mitosis or meiosis. Choice A is incorrect because DNA recombination occurs during prophase I of meiosis I. Choice B is incorrect because sister chromatids separate during the later stages of mitosis and meiosis II. Choice C is incorrect because the nuclear membrane dissolves during prophase of mitosis or meiosis. Choice D is incorrect because RNA replication is not a part of interphase.
