Mitochondrial DNA is the small circular chromosome found inside mitochondria. These organelles , found in all eukaryotic cells, are the powerhouse of the cell. [ 1 ] The mitochondria, and thus mitochondrial DNA, are passed exclusively from mother to offspring through the egg cell .
Mitochondrial matrix has a pH of about 7.8, which is higher than the pH of the intermembrane space of the mitochondria, which is around 7.0–7.4. [5] Mitochondrial DNA was discovered by Nash and Margit in 1963. One to many double stranded mainly circular DNA is present in mitochondrial matrix. Mitochondrial DNA is 1% of total DNA of a cell.
A mitochondrion (pl. mitochondria) is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi.Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy.

Mitochondrial diseases range in severity from asymptomatic to fatal, and are most commonly due to inherited rather than acquired mutations of mitochondrial DNA. A given mitochondrial mutation can cause various diseases depending on the severity of the problem in the mitochondria and the tissue the affected mitochondria are in.
The mitochondrial genome is a circular DNA molecule distinct from nuclear DNA. Although the mitochondrial DNA is very small compared to nuclear chromosomes, [2] it codes for 13 proteins involved in mitochondrial energy production and specific tRNAs. Foreign genetic material (most commonly DNA) can also be artificially introduced into the cell ...
The set of DNA molecules contained within mitochondria, usually one or more circular plasmids representing a semi-autonomous genome which is physically separate from and functionally independent of the chromosomal DNA in the cell's nucleus. The mitochondrial genome encodes many unique enzymes found only in mitochondria. mitochondrial fusion ...
A Chicago woman was just weeks away from giving birth when a nagging cough led to a shocking medical discovery. MaKenna Lauterbach shared her harrowing story with Fox News Digital.
In biology, matrix (pl.: matrices) is the material (or tissue) in between a eukaryotic organism's cells. The structure of connective tissues is an extracellular matrix. Fingernails and toenails grow from matrices. It is found in various connective tissues. It serves as a jelly-like structure instead of cytoplasm in connective tissue.
