kinetoplast
A kinetoplast is a network of circular DNA (called kDNA) inside a large mitochondrion that contains many copies of the mitochondrial genome. The most common kinetoplast structure is a disk, but they have been observed in other arrangements. Kinetoplasts are only found in protozoa of the class Kinetoplastida. The variation in the structures of kinetoplasts may reflect phylogenic relationships between kinetoplastids. A kinetoplast is usually adjacent to the organism's flagellar basal body, suggesting that it is tightly bound to the cytoskeleton. In ''Trypanosoma brucei'' this cytoskeletal connection is called the tripartite attachment complex and includes the protein p166.
==''Trypanosoma''==
In trypanosomes, a group of flagellated protozoans, the kinetoplast exists as a dense granule of DNA within the large mitochondrion. ''Trypanosoma brucei'', the parasite which causes African trypanosomiasis (African sleeping sickness), is an example of a trypanosome with a kinetoplast. Its kinetoplast is easily visible in samples stained with DAPI, a fluorescent DNA stain, or by the use of fluorescent in situ hybridization (FISH) with BrdU, a thymidine analogue.
