Chromatins are just a combination of DNA, histones(a type of proteins) and RNA. Strands of DNA are considered as chromatins and when these strands combine, this forms the chromosome. Chromatin is untangled and unfolded DNA, while chromosome is condensed DNA.The chromatin condenses into chromosome during mitosis.he nucleosomes condense to form a chromatin fiber. Chromatin fiber organises into Chromosomes upon cell division. The chromatin is elaborately arranged and paired in mitosis. Sister chromatids are formed in case of meiosis along with pairing.
Best Answer: chromosomes are tiny x looking structures in a cell that package chromatids which are joineed by Histones. Inside this Chromatids are the genetic sequences know as deoxyribonucleic acid (DNA). All of this is located in the nucleus of the cell.hromosomes are made up of tightly wound bands of DNA, which is made up of Four nucleotide bases, adenine, guanine, cytosine, and thymine, with sugar and phospate bonds.
