Introduction: Chromatin is a complex macromolecule, which contains DNA, protein as well as RNA. Chromosome is a densely packaged chromatin. It is a thread like structure present in nucleus of the cell. A chromosome has a constriction point in the middle called centromere. Chromosomes duplicate during the process of cell division and form sister chromatids, which further gets separted into two chromosomes.

Explanation of Solution

Chromosome, chromatin, and chromatid all occur in the nucleus of the cells, but have some basic differences. The difference between chromosomes, chromatin, and chromatid is shown below:

CriteriaChromosomesChromatinChromatid
DefinitionChromosomes is condensed form of chromatin, which contains DNA and proteins.Chromatin is very fine interdispersed form of DNA associated with protein and RNA.The identical pieces of DNA that is held together by  acentromere and pulled apart in the cell division process to make new identical cells that are called sister chromatids.
