If a cell contains a set of duplicated chromosomes, does it contain any more genetic information than the cell before the chromosomes were duplicated?
No, they cells are basically an exact replica of the DNA.
What is the significance of the fact that chromosomes condense before they are moved?
They are smaller and they are easier to move.
How are the chromosome copies, called sister chromatids, separated from each other?
The spindle fibers pull them apart.
What would happen if the sister chromatids failed to separate?
They there would be birth defects like down syndrome.
What events could promote genetic variation during mitosis?
The splitting of the chromosomes.
What problems could occur with a loss of cell cycle control?
It would fail to reproduce and eventually die. All the old cells would die, leaving no remaining cells.
