Chapter 6 Chromatin and chromosomes By Benjamin Lewin 6.2 Chromatin is divided into euchromatin and heterochromatin Individual chromosomes can be seen only during mitosis. During interphase, the general mass of chromatin is in the form of euchromatin.

Cell Division

Cell Division

Cell Division. Chromosomes. Are made of DNA Each chromosome consists of sister chromatids attached at a centromere. Cell Cycle. During the cell cycle, a cell grows, prepares for division, and divides to form 2 daughter cells, each with each of which then begins the cycle again.
