WebWhat is the Function of Chromatin? Chromatin is a way for DNA to take up less space in the nucleus of the cell. It also keeps the nucleus organized when the cell divides to form two cells.

WebPrior to S-phase each chromosome is a single chromatin fiber. During S-phase the DNA is replicated and this results in two chromatin fibers (known as sister chromatids). However, these chromatin fibers are attached to each other at the centromere and together they make up a post S-phase chromosome. WebChromosomes. Each species has its own characteristic number of chromosomes. Humans, for instance, have 46 chromosomes in a typical body cell (somatic cell), while dogs have 78 ^1 1.
