Does chromatin contain chromatids?

1 Answer

They are actually one and the same.

Explanation:

In cell cycle, there are two phases called the interphase and mitosis. During interphase, the nuclei of the cells are not seen easily because the genetic materials are uncoiled or loose; they tend to look like thin fibers. This uncoiled, loose thin fibers of genetic material are called as chromatin . On the other hand, as cell division (mitosis) starts, the chromatin starts to condense making it more visible under the microscope, utilizing the appropriate staining reagent (aceto-carmine). The condensed version of the chromatin is now called as chromosome.

We already know that the chromosome looks like an "X" as seen from the picture below

Technically, chromosomes are composed of two strands known as the chromatid. Two chromatids of the same length are joined together by a centromere (indicated as the glowing portion in the picture).

Therefore to answer this question, they are actually one and the same.
