Additionally, DNA in eukaryotic cells is stored in double-stranded chromosomes that are condensed by histones. In contrast, prokaryotic cells have one primary circular chromosome and various plasmids, which are small rings of DNA.
WebbIn molecular biology, a histone octamer is the eight-protein complex found at the center of a nucleosome core particle. It consists of two copies of each of the four core histone proteins ( H2A, H2B, H3, and H4 ). The octamer assembles when a tetramer, containing two copies of H3 and two of H4, complexes with two H2A/H2B dimers. Webbeukaryotes [1].
