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.
Cell Membrane and neuron. The outer cell membrane plays a delimiting and protective for the cell itself. The function of the plasma membrane is to divide the internal environment from the external one in order to constantly regulate the passage in and out of all the substances.nside there is another structure called nucleolus. The nucleolus is a region of the cell nucleus responsible for the synthesis of ribosomal RNA (rRNA). The nucleolus is not an organelle but a dense region of genetic material and protein.
