Why is the answer false for this question?

True or false? After a cell undergoes mitosis and begins interphase, it contains twice as much genetic material as it will at the end of interphase.





Shouldn't the answer be true? Because during interphase the DNA copies, so when it gets to the end of interphase shouldn't there be twice as much DNA as there was to begin with?





I put true but answer is false according to my book. I got this off of a provincial exam so I don't think their answer could be wrong. But I don't understand why it's false, can someone explain?Why is the answer false for this question?
omg. this exact question came out on my test.





question is trying to say: ';at the beginning of interphase, the genetic material will be double the amount, compared to the number at the end of interphase';. or that ';genetic material is doubled before interphase'; or that ';genetic material divides during interphase.';





stupid weirdo provincial people. the answer should be false, by the way.Why is the answer false for this question?
The answer is false. After a cell undergoes mitosis, it has just divided and contains a 2N number of chromosomes-that is 23 pairs. During interphase the DNA replicates and the cell then contains 46 pairs or 4N chromosomes. So, at the beginning of interphase, the cell is 2N, at the end it is 4N. If they rephrased the question to say that the cell would have half as much genetic material at the end of interphase, the answer would be true.





As for the previous post, there is no such thing as what they say. How can DNA be impuned? Google the word they wrote, dextrastosin. No such thing.
it's because the question is saying that at the BEGINNING of interphase, it will have twice as much. . . but it really has twice as much at the END of interphase. you had the idea right, maybe just read the question wrong.
Your logic is right, the question is just phrased funny. It says that at the BEGINNING of interphase you have twice as much as at the END. As you said, at the END you have twice as much as at the beginning.
