Electron microscopic analysis of Vicia faba mitochondrial DNA revealed two different types of circular DNA molecules. The class of small DNA molecules consisted mainly of circles near 1.6 kb in size, although a number of molecules were 2–3-times longer. Large molecules ranged from 27 to 120 kb...
Using genome sequencing project data, we describe here the complete sequence of a 29,270-bp circular DNA molecule that presents mitochondrial features (such as oxidative phosphorylation complex I subunits) but lacks complexes III, IV and V. Transmission electron microscopy analyses reveal that this ...
MtDNA is a circular double-stranded DNA molecule approximately 16.5 kb in length in humans, which consists of a heavy chain (H-chain) rich in G and a light chain (L-chain) rich in C. Notably, the H-chain encodes the majority of mtDNA (Anderson et al. 1981). Furthermore, mtDNA ...
minicircular DNA molecules. These clones were used to probe Southern blots of mitochondrial genomes from six cytoplasmic male-sterile (CMS) and five male-fertile (MF) lines ofS. bicolor, as well as Southern blots of IS1112C chloroplast, kafir chloroplast, IS1112C nuclear, and kafir nuclear ...
mitochondrial DNA (mtDNA) the DNA GENOME in the MITOCHONDRION that codes for a number of the organelle's functions. The genome is replicated and transcribed by a separate set of ENZYMES from those of the eukaryotic cell NUCLEUS. In METAZOANS the mtDNA is generally circular, and there appear to...
They contain their own genetic material, a circular chromosome termed mitochondrial DNA (mtDNA)1, differentiating them from most other eukaryotic subcellular structures with the exception of chloroplasts. It is proposed that mitochondria originated from an endosymbiotic event between an α-proteobacterial ...
Mitochondria also contain in their matrix single or double circular and double-stranded DNA molecules called mt DNA and also the 55S ribosomes, called mitoribosomes. Since mitochondria can synthesize 10 percent of their proteins in their own protein-synthetic machinery, they are considered assemi-...
Mitochondria have several copies of the mitochondrial genome that consists of a 16.5 kb circular DNA molecule [24] that, in turn, provides the template for 13 essential proteins of the respiratory chain. In a mitochondrion there are more than 900 proteins, most of them being encoded by the nu...

Mitochondria are double membrane-bound organelles of a eukaryote cell containing mitochondrial DNA (mtDNA) [3,4], which is the circular chromosome found inside mitochondria [5], and play an important role in energy generation through a breakdown of energy sources such as pyruvate, fatty acids and...
