Question

4 differences between chromatin fibre and chromosomes class 10th

Answer 1

Hey Friend......☺

Here is your answer

In the nucleus, the DNA double helix is packaged by special proteins (histones) to form a complex called chromatin. The chromatin undergoes further condensation to form the chromosome. So while the chromatin is a lower order of DNA organization, chromosomes are the higher order of DNA organization. An organism’s genetic content is counted in terms of the chromosome pairs present. e.g. humans have 23 pairs of chromosomes.

Hopping it helps you

Thanks :-)

Answer 2

The chromatin fibers are the network of DNA strands scattered in the nucleus. The chromatin is what we see most of the time in the nucleus. Only during the cell division, these fibers undergo condensation and forms chromosome.
Chromosomes are highly condensed chromatin fibers with the help of special proteins called histones in the eukaryotic cells.

This is just what you need to know in 10th grade....

Oh, you want 4 differences. Here it goes..

1.A chromosome is highly condensed chromatin while chromatin is uncoiled chromosome.
2. Chromosome contains histone proteins that packs the chromatin fibers.
The chromatin is devoid of these packing proteins.
3.The chromosome contains different contrictions one of them is centromere which the chromatin fibers lack of.
4.The chromosome is formed only during cell division. DNA stay mostly as chromatin fibers.
