Question

Does chromatin contain RNA?

Answer 1

Hint: Chromatin is present inside the nucleus of eukaryotic cells, where it contains nucleic acids and protein in the form of beads on string in which DNA is the main component that helps to perform several functions. Condensation of chromatin fibres makes up single-stranded chromosomes.

Complete answer:
In eukaryotes, chromatin is present inside the nucleus with complex macromolecules or nucleic acids like DNA and RNA, which helps to make protein. RNA strands develop from DNA as an integral component that helps in the structural organisation of cells as RNA performs gene silencing with the help of RNAi.
The chromatin forms a fine overlapping and coiled fibre which appears in a form of a network known as a chromatin network and at the time of division this network condenses to form chromosomes, which bear a constricted part centromere. The chromatin gets packed with the help of histone protein present in the form of beads on string in the chromatin thread. The chromatin is distinguished into euchromatin and heterochromatin. The euchromatin is narrow, light and diffused which forms the bulk of chromatin and it is 30- 80 Å in thickness, with the presence of active genes whereas heterochromatin is wide, dark and condense in form of granules and 250 Å in thickness, without the presence of active genes.

Note:
Chromatin is observed during the interphase of cell division. It is influenced by several factors like pH, temperature, nature, concentration etc. The whole chromatin does not function for transcription or formation of RNA, only a small portion of euchromatin containing acid proteins take part in transcription and RNA formation.
