16. What are the substances that constitute the chromatin? What is the difference between chromatin and chromosome?

T chromatins make up chromosomes. Chromatins are just a combination of DNA, histones (a type of proteins) and RNA. Strands of DNA are considered as chromatins and when these strands combine, this forms the chromosome. Chromatin is untangled and unfolded DNA, while chromosome is condensed DNA. T he chromatin, dispersed in the nucleus, is a set of filamentous DNA molecules associated to nuclear proteins called histones. Each DNA filament is a double helix of DNA and thus a chromosome.
