Changes

Prokaryotic DNA lacks histones (packaging [[protein]]s), although other packaging proteins are present, and molecules have easier access to DNA compared with eukaryotes. They generally have efficient genomes, with little sequence other than coding sequence or regulatory sequence. Transcription leads to translation with no intermediate processing, which allows several genes to be encoded in a single transcriptional unit (a polycistron). No bacterial [[intron]]s exist. They have small (70S) ribosomes.
