Mitochondrial DNA from human cells is a circular DNA molecule of about 15,000 base pairs.


The mRNAs transcribed from the mitochondrial DNA (mtDNA) code mostly for highly hydrophobic proteins. The reason for having this biosynthetic machinery inside the mitochondrion is that there is no other way of getting these very hydrophobic proteins inside the organelle.

The three largest subunits of cytochrome oxidase and one protein subunit of the cytochrome b-c1 complex are made on mitoribosomes.
