Chromsomes and Chromatin?

are chromosomes and chromatin composed of the same chemical? True or False True
True. Deoxyribonucleic sour bound in histones and other proteins.
Chromosomes are chromatin that have been supercoiled to a much greater point, in preparation for the vicissitudes of mitosis or meiosis.
lol.true, they are made of matching chemical i.e, dna and histone protien molecules. The difference between the two is only structural. Chromatin is the uncoiled,dense and loosly full nuclear material inside the nucleus,whereas during cell division, the chromatin(same matter chemically) coiles up and shortens to become a chromosome<<<basically alike thing, with the sole purpose more condensed(closely packed).
I said "lol" cuz ur ques reminded me of how i used to have problems for a long while next to this ques in dignified school (also beside the difference between chromosomes and chromatids).
Hope this helps; soak up ur bio =D
True
True. Chromosomes and chromatin's are composed of the same chemical and the first name of that chemical is deoxyribonucleic acid DNA surrounded by short. Its just that chromatin is a single strand of DNA ,while chromosomes are bundles of chromatin's.
Chromosomes and chromatin are essentially impossible to tell apart material. The just difference is that chromosomes look thick and condensed beneath the microscope while chromatin looks like this fibrils that are largely dispersed. During the cell cycle, the chromatin threads endure replication to produce 2 sister chromatids held by a centromere. This is then call a chromosome. And this happens during the S phase of cell division
