What is the difference between chromatin and dna

The reason that chromatin is important is that it's a pretty good packing trick to get all the DNA inside a cell. If one took the DNA inside of one cell and stretched it out end to end, it would be about a yard long. Each cell is about a hundredth of a millimeter across, so it's pretty good packing job for the yard of DNA within something that is a hundredth of a millimeter in diameter.

And the chromatin does that by wrapping and re-wrapping the DNA in a very tight coil. And that arrangement is called chromatin. We have tried to cover up sufficient points for the difference between chromatin and chromosomes. We hope that if the question comes - differentiate between chromatin and chromosomes, you have sufficient points for answering the same.

For this, we'll be explaining the structure of chromatins and chromosomes one by one. Structural Entity: Nucleosomes are the structural entity of chromatin. Size: 10nm approx. Representation: DNA overlapping nucleoproteins by a magnitude of Chromatin also helps in the formation of chromosomes.

Structural Entity: Chromatins fibers are the structural entity of chromosomes. We hope that the structural difference between the chromatin and chromosomes is very much clear. So if you are asked to differentiate between chromatin and chromosome, based on structure, you have a sufficient answer.

Chromatin Shows the Following Metabolic Activities:. DNA Replication: DNA replication is the process by which genetic material is passed from the parent cell to the daughter cells.

When a cell grows, it must replicate the DNA to carry forward the genetic information, which is done by replicating the dna. Chromosomes don't exhibit any metabolic activities.

The reason behind this is the structure of the chromosomes. Since they are tightly coiled, it becomes unmanageable for the chromosomes to perform metabolism. We have differentiated chromatin and chromosomes based on metabolic activities. If the question arises- explain the metabolic activities in chromatin, we have covered sufficient points.

In human cells, the parent cell has 46 chromosomes 23 pairs , so the cells produced by meiosis have 23 chromosomes. These cells will become gametes. It is commonly accepted that the loop domain represents the basic structural unit of eukaryotic chromatin associated with DNA replication, gene expression and higher order packaging.

Each individual nucleosome core particle consists of a complex of eight histone proteins- two molecules each of histones H2A ….. The histone octamer forms a protein core around which the double-stranded DNA is wound. Begin typing your search term above and press enter to search. Press ESC to cancel.
