DNA Structure and Replication

ID #1707

A diagram in handout shows nucleus of a cell that has just entered mitosis still has more euchromatin than heterochromatin. Does this mean that the cell continues to condense its chromatin even after it enters mitosis, or is it unnecessary for all of the chromatin to be in the most condensed form (the X-shaped chromosomes) during mitosis?


This is a "snapshot" in time as the chromatin is being condensed. The chromatin from a given pair of sister chromatids will continue to be condensed into higher and higher levels of heterochromatin until it's all packaged into one of those "X-shaped" structures.
