Lesson Summary. The nucleoid region is the irregularly-shaped section of a prokaryotic cell where DNA is housed. It lacks the membrane that is found around the nucleus of eukaryotic cells. In addition to DNA, the nucleoid may also contain RNA, proteins, and enzymes that can be used for cellular processes.
Prokaryotic cells do not contain nuclei or other membrane-bound organelles. In fact, the word  prokaryote  literally means before the nucleus.. The nucleoid is simply the area of a prokaryotic cell in which the chromosomal DNA is located.hereas eukaryotes wrap their DNA around proteins called histones to help package the DNA into smaller spaces, most prokaryotes do not have histones (with the exception of those species in the domain Archaea).
