Eukaryotic chromosomes structure

WebUnderstanding: Eukaryotic chromosomes are linear DNA molecules associated with histone proteins. Eukaryotic DNA is linear and associate with histone proteins in a structure called the nucleosome. During interphase, the DNA is not super-coiled into chromosomes; it is in a loose form called chromatin. WebTo prevent the loss of genes as chromosome ends wear down, the tips of eukaryotic chromosomes have specialized DNA “caps” called telomeres. Telomeres consist of hundreds or thousands of repeats of the same short DNA sequence, which varies between organisms but is 5'-TTAGGG-3' in humans and other mammals.
