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.
The functions of smooth endoplasmic reticulum are different from the rough variety. It plays a different role in every type of eukaryotic cell. Its primary function is that of serving as a site for enzyme action and storing various ions and enzymes for cellular functions.he whole endoplasmic reticulum is a continuously connected network of tubules, cisterns, and vesicles that is spread throughout the cytoplasm and is covered with a special membrane. The whole assembly takes up 10% of the total cell volume.
