Chromatin Structure
The formation of chromatin is the first step in a series of folding events that reduce the length of DNA 10,000 fold from its extended form into a compact mitotic chromosome. An average human mitotic chromosome 5 microns in length contains 5 cm of DNA. In the electron microscope, chromosomes appear to be composed of fibers 250 to 300 Å in ...

The difference between chromatin, chromatid and chromosome
Therefore, chromosomes can be found in 3 forms: thread-like chromatin (during G1 of interphase), thread-like sister chromatids (during S-phase of interphase) and the condensed, visible form (during mitosis). When a cell divides, the sister chromatids separate, and each daughter cell receives one of the strands.
Chromosomal DNA and Its Packaging in the Chromatin Fiber
Each chromosome consists of a single, enormously long linear DNA molecule associated with proteins that fold and pack the fine DNA thread into a more compact structure. The complex of DNA and protein is called chromatin (from the Greek chroma, “color,” because of …
