Web2 aug. 2015 · DNA for most of organisms is very large that it is very difficult to organize it if kept randomly. So, to organize the large DNA, DNA is compressed into chromatin (10nm thick fibre) which is then compressed to thicker chromatin (30nm thick fibre) then again it is compressed into the form of chromosome. WebPhysically speaking, DNA is a long string of paired chemical units (nucleotides) that come in four different types, and it carries information organized into units called genes. Genes … WebWhen chromatin condenses, you can see that eukaryotic DNA is not just one long string. Instead, it’s broken up into separate, linear pieces called chromosomes.
