What is chromatin in a cell? Chromatin is a complex of nucleic acids (e.g. DNA or RNA) and proteins (e.g. histones). It was identified in 1882. Initially, it was thought of as just a colored substance in a nucleus, however, later it was found that chromatin is characterized as proteins attached to DNA, and DNA was … See more The histone protein and DNA have an equal mass in eukaryotic chromatin (although there are also some cells with non-histone proteins … See more There are two forms of chromatin: (1) euchromatin and (2) heterochromatin. Euchromatin is less condensed and can be transcribed whereas heterochromatin is highly condensed … See more Although all the three structures i.e. chromatin, chromosomes, and chromatids are present in the nucleus of the cell and are composed of DNA, however, they are uniquely identified as … See more Initially, chromatin was considered as the substance that gives color to the cell nucleus. Later on, it was found that it is not just a coloring substance but is one of the most important DNA expression regulators. … See more WebApr 10, 2024 · While the activities of chromatin have been identified, the function of chromosomes is critical for mutation, regeneration, cell division, variation, and inheritance.

Chromatin is a complex of DNA and protein found in eukaryotic cells. The primary function is to package long DNA molecules into more compact, denser structures. This prevents the strands from becoming tangled and also plays important roles in reinforcing the DNA during cell division, preventing DNA damage, and regulating gene expression and DNA replication.
