Suppose those chromosomes are discovered in a cell nucleus throughout prophase. A is equal to B, and C is identical to D in dating among chromatids.
During prophase, the complicated DNA and proteins contained within the nucleus, called chromatin, condenses. The chromatin coils and turns increasingly more compact, ensuing in the formation of visible chromosomes.
In the course of prophase II, the chromosomes condense, and a brand new set of spindle fibers bureaucracy. The chromosomes begin transferring closer to the equator of the cellular. at some stage in metaphase II, the centromeres of the paired chromatids align alongside the equatorial plate in each cell.
