Document Summary
Aside: mitos contain their own systems for replication of mtdna, transcription of mtdna, and translation of mt mrnas. Most of the components of these systems are encoded by nuclear genes and imported into mitos. In general, there is no relationship with the components of similar systems in the nucleus or cytosol. Most mtdnas are circular in form (all on the table = circular) Names for protein coding genes are given beside the name of the complex. Size of mtdnas does not always correlate with the number of genes encoded on that dna ex. Note: the relatively large size of a. t. mtdna (and other land plants) - some codes for functional genes, but much is also duplications and junk dna. Note that s. cerevisiae and plasmodium have no complex i. These organisms have simple nadh dehydrogenases coded in the nucleus and imported to mitos.
