kinetoplast

 [kĭ-ne´to-plast]
an accessory body found in many protozoa, primarily the Mastigophora; it contains DNA and replicates independently.

ki·ne·to·plast

(ki-nē'tō-plast, ki-net'ō-),
An intensely staining rod-shaped, diskoid, or spheric extranuclear DNA structure found in parasitic flagellates (family Trypanosomatidae) near the base of the flagellum, behind the blepharoplast, and often at right angles to the nucleus. Visible by light microscopy, electron micrographs reveal it as part of a single giant mitochondrion filling most of the cytoplasm of amastigote flagellates. Identifying kinetoplast as kDNA distinguishes it from nuclear DNA(nDNA). The kinetoplast divides independently, but with the basal body, before nuclear division. Kinetoplast formerly included parabasal body and blepharoplast in a locomotory apparatus but is now recognized as a distinct organelle of most trypanosomatids.

kinetoplast

/ki·ne·to·plast/ (ki-nēt´o-plast) a structure associated with the basal body in many protozoa, primarily the Mastigophora; it is rich in DNA and, like the basal body, it replicates independently.

(kə-nĕt′ə-plăst′, -nē′tə-, kī-)
n.
A loop of DNA located in a large mitochondrion that lies near the base of the flagellum in certain protozoans.
