In prokaryotes, the DNA (chromosome) is in contact with the cellular cytoplasm and is not in a housed membrane-bound nucleus. In eukaryotes, however, the DNA takes the form of compact chromosomes separated from the rest of the cell by a nuclear membrane (also called a nuclear envelope).Eukaryotic cells also contain a variety of structures and organelles not present in prokaryotic cells.ver time, portions of the DNA from the other prokaryote remaining in the cytoplasmic part of the cell may or may not have been incoporated into the new eukaryotic nucleus (Figure 3). Figure 3: Origin of a eukaryotic cell. A prokaryotic host cell incorporates another prokaryotic cell.
HIV can have devastating effects on the body. There may not be any serious symptoms for ten years or more, but if untreated the fatal illness AIDS will develop.HIV seriously affects the immune system and leaves it open to infection from numerous sources.People with HIV can develop cancers such as Kaposi's sarcoma, lymphoma, cervical cancer, and cancer of the rectum.
