Missense mutation
A type of mutation that results in a single amino acid in the translated gene, product.

Mitochondria
A membrane-bounded structure in the interior of the cell that generates energy for the cell. Generally inherited from the mother.
2. These are energy transforming structures found in all cells. Each mitochondrion has a circular chromosome with a small number of genes on it. This chromosome resembles that of the bacteria-like ancestor of the mitochondria.

Mitochondrial DNA
DNA found in the mitochondrion, a small round body in most cells. Because mitochondria are generally carried in egg cells but not in sperm, mitochondrial DNA is passed to offspring from mothers, but not fathers.
2. The genetic material found in mitochondria, the organelles that generate energy for the cell. Not inherited in the same fashion as nucleic DNA.
3. The genetic material of the mitochondria, the organelles that generate energy for the cell.

Mitochondrion
A kind of organelle in eukaryotic cells. Mitochondria produce enzymes to convert food to energy. They contain DNA coding for some mitochondrial proteins.

Mitosis
The process of nuclear division in cells that produces daughter cells that are genetically identical to each other and parent cell.

2. The nuclear division producing two daughter nuclei identical to the origin nucleus. A type of nuclear division that produces two daughter nuclei identical to the parent nucleus normally just prior to cell division.

3. A form of cell division resulting in the production of two cells, each of which has the same chromosomal complement as the original parent bell.

4. Cell division. All cell division in multicellular organisms occurs by mitosis except for the special division called meiosis that generates the gametes. 

5. The nuclear division producing two daughter nuclei identical to the original nucleus; divided into four stages of prophase, metaphase anaphase, and telophase.
