Chromosome Theory of Inheritance
... DNA is the basis of life. It contains a set of instructions for building all of the proteins and RNA found in a cell. Those instructions are written in a code called the genetic code. The code consists of 4 bases, Adenine, Cytosine, Guanine, and Thymine, often referred to as A, C, G, and T. The 4 ba ...

For example, if the wrong base is inserted during replication (a mutation) and this mistake happens to be in the middle of an important gene, it could result in a non-functional protein.

Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants, in the chloroplast.In humans, mitochondrial DNA can be assessed as the smallest chromosome coding for 37 genes and containing approximately 16,600 base pairs. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. In most species, including humans, mtDNA is inherited solely from the mother.The DNA sequence of mtDNA has been determined from a large number of organisms and individuals (including some organisms that are extinct), and the comparison of those DNA sequences represents a mainstay of phylogenetics, in that it allows biologists to elucidate the evolutionary relationships among species. It also permits an examination of the relatedness of populations, and so has become important in anthropology and field biology.
