WebThe basic repeating structural (and functional) unit of chromatin is the nucleosome, which contains eight histone proteins and about 146 base pairs of DNA (Van Holde, 1988; Wolffe, 1999). WebApr 8, 2024 · Chromosomes contain telomeres, centromeres, and an origin of replication apart from genes. Chromosomes are condensed 10,000 times more than the normal DNA double helix, whereas the Chromatins are condensed 50 times than the normal DNA double helix. Hence, this is the main difference between chromosomes and chromatin.
