Students have asked these similar questions
In which phase of the cell cycle the chromosomes exist as two sister chromatids??
The same chromosome can look very different depending on when in meiosis it is observed. Explain fully why this is so and also why the chromosome is less condensed during some parts of the cell cycle? How many DNA molecules does each chromosome contain at the beginning of Prophase I? Use the following terms in your explanation: chromatin, histone, chromatid, centromere.
Under normal conditions, what happens to the cell cycle if the chromosomes fail to separate properly at anaphase?
