A protein found in the mitochondria that exists in two forms. The first form prevents the mitochondrial membrane from destabilizing. When mtCK is inactivated by free radicals, it transforms to the second form, making the membrane less stable.

Mitochondria are a major source of superoxide, formed by the one-electron reduction of oxygen during electron transport. Superoxide initiates oxidative damage to phospholipids, proteins and nucleic acids.

mitochondrial DNA (mtDNA)
Circular or linear DNA of the mitochondria. It codes for only a small but essential part of the mitochondrial proteins and for genes for tRNAs and rRNAs.

Mitochondria and plastids
Mitochondria are organelles found in nearly all eukaryotes. They are surrounded by double membranes, the inner of which is folded into invaginations called cristae, where aerobic respiration takes place.

Mitochondrial ribosomes; these more closely resemble prokaryotic ribosomes than cytoplasmic ribosomes of the cells in which they are found, though they are even smaller and have fewer proteins than bacterial ribosomes.

Mitochondrial and plastid genomes contain much less genetic material than their hypothesized endosymbiont ancestors, yet still contain almost as many organelle-specific proteins as are present in those ancestors.

Mitochondria
Small organelles in the cell where energy from electron transport between molecules is converted into energy for biological activity. Mitochondria also possess their own genome, which is inherited maternally.

Mitochondrial DNA is the small piece of DNA that is found inside our mitochondria. Our mitochondria are little powerhouses in our cells. These are the little structures that make ATP and other goodies that the cell depends on for survival.

Mitochondria contain their own DNA (termed mDNA) and are thought to represent bacteria-like organisms incorporated into eukaryotic cells over 700 million years ago (perhaps even as far back as 1.5 billion years ago).

Chloroplasts and mitochondria are organelles within eukaryotic cells (cells of organisms other than bacteria, which do not have organelles). These organelles have their own genetic material.

Genome -- all of the genes carried by a single gamete; the DNA content of an individual, which includes all 44 autosomes, 2 sex chromosomes, and the mitochondrial DNA. Genotype -- genetic constitution of an organism.

Mitochondrial DNA Mitochondria, and chloroplasts in plants, carry their own small chromosomes, usually in multiple copies per organelle. These carry a limited number of genes which code for rRNA, tRNA and a few organelle proteins.

Numerous variations of the standard genetic code are found in mitochondria, energy-burning organelles.
