Summary
| Description |
English: Basic units of genomic organization in bacteria and eukaryotes Genomic DNA, depicted as a grey line, is negatively supercoiled in both bacteria and eukaryotes. However, the negatively supercoiled DNA is organized in the plectonemic form in bacteria, whereas it is organized in the toroidal form in eukaryotes. Nucleoid associated proteins (NAPs), shown as colored spheres, restrain half of the plectonemic supercoils, whereas almost all of the toroidal supercoils are induced as well as restrained by nucleosomes (colored orange), formed by wrapping of DNA around histones. |
