During anaphase of mitosis, the sister chromatids split apart to go to the opposite end of the cell. What would happen to the daughter cells if a pair of sister chromatids failed to split in anaphase?
One daughter cell will receive an extra chromosome, and one will be short a chromosome.
In anaphase, sister chromatids separate and move towards the opposite ends of the cell. If this process fails for a pair of sister chromatids, one daughter cell will end up with an additional chromosome and the other will have one less chromosome.
This is incorrect. If sister chromatids fail to separate during anaphase, they will not be lost from both cells. Instead, both chromatids will end up in one daughter cell, leaving the other short of one chromosome.
This is incorrect. While errors in mitosis can lead to a halt in the cell cycle, the failure of a pair of sister chromatids to separate does not necessarily stop mitosis. The process can continue, creating two daughter cells with an abnormal chromosome number.
This is incorrect. If the sister chromatids do not separate, one cell will receive both chromatids (an extra chromosome) and the other will not receive any (resulting in one less chromosome).
This is correct. The failure of sister chromatids to separate during anaphase results in one daughter cell receiving both chromatids (thus, an extra chromosome), while the other daughter cell does not receive any (thus, it is short a chromosome).
The separation of sister chromatids during anaphase is a crucial step in mitosis to ensure that each daughter cell receives an equal number of chromosomes. If this separation fails for a pair of sister chromatids, it results in an unequal distribution of chromosomes, with one daughter cell receiving an extra chromosome and the other being short a chromosome. This leads to chromosomal abnormalities in the daughter cells, which can have significant biological consequences.
