Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. … Under the microscope in its extended form, chromatin looks like beads on a string. The beads are called nucleosomes. Each nucleosome is composed of DNA wrapped around eight proteins called histones.
Do chromatin contains DNA and RNA?
Yes, chromatin contains RNA. It is an integral part of chromatin and plays a role in the structural organisation. Around 2-5% of total nucleic acids present in chromatin are RNA. Stay tuned to BYJU’S to learn similar questions and important points about the structure of DNA, RNA, Nucleus and other cellular components.
What is the difference between DNA and chromatin?
The DNA is packaged by special proteins called histones to form chromatin. The chromatin further condenses to form chromosomes.
|Difference between Chromosomes and Chromatin|
|Composed of nucleosomes||They are condensed chromatin fibers|
Is RNA part of chromatin?
Here, we report results indicating that RNA plays a general structural role in eukaryotic chromatin. Our results indicate that purified chromatin contains significant amounts of RNA (2%–5% of total nucleic acids).
Is chromatin made up of RNA?
Chromatin is a complex of macromolecules composed of DNA, RNA, and protein, which is found inside the nucleus of eukaryotic cells.
What is the difference between DNA and gene?
In general, a gene is a short section of DNA while DNA- Deoxyribonucleic acid is a molecule. The DNA plays an important role to carry the genetic instructions or the hereditary materials.
Difference Between Gene and DNA.
|A gene is present on a chromosome.||DNA is present within the nucleus of the cell.|
