What is chromatin
Condensed DNA or RNA
Chromatin is a complex of DNA, histone proteins, and other non-histone proteins that make up the structure of chromosomes within the nucleus of eukaryotic cells. It serves to tightly package the DNA into a compact, organized structure in order to allow for efficient storage and transmission of genetic information. Chromatin also plays a key role in regulating gene expression by controlling the access of transcription factors and other regulatory proteins to the DNA. There are two basic types of chromatin: euchromatin and heterochromatin, which differ in their levels of condensation and accessibility to the machinery that transcribes DNA into RNA.
