WebbThe five main histones present in chromatin are H2A, H2B, H3, H4, and H1, but H1 is not part of the histone octomer. Each histone also has a flexible amino tail that have various lysine and arginine residues and extends beyond the core. These tails are very important because covalent modifications of them alter the DNA affinity of the histones. WebbIn eukaryotes, the vast majority of DNA synthesis occurs during S phase of the cell cycle, and the entire genome must be unwound and duplicated to form two daughter copies. During G 2, any damaged DNA or replication errors are corrected. ... After the deposition of histones H3-H4, nucleosomes form by the association of histone H2A-H2B. WebbThe DNA in eukaryotes is stored within the nucleus, while DNA is stored in the cytoplasm of prokaryotes. 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. gator 6 wheeler
