All animal cells are made up of two genomes, the nuclear genome with 10,000 s of protein
coding genes and the
mitochondrial genome with 13 protein - encoding
genes.
Several mutations were found in
genes coding the machinery that makes
mitochondrial proteins, and so would probably hinder mitochondria's ability to make the chemical fuel called ATP, which is used by normal cells.
By comparing proteomic and RNA - sequencing data from people on different exercise programs, the researchers found evidence that exercise encourages the cell to make more RNA copies of
genes coding for
mitochondrial proteins and proteins responsible for muscle growth.
To narrow down the suspects in the US Airways crash, the Smithsonian lab's Carla Dove isolated and sequenced a small piece of a
mitochondrial gene — known in the field as a DNA bar
code.
The branch uniting the fungi and animals is well - supported based on a number of molecular phylogenetic datasets, including the nuclear small subunit ribosomal RNA
gene (Wainwright et al., 1993; Bruns et al. 1993), unique and shared sequence insertions in proteins such as elongation factor 1α (Baldauf and Palmer, 1993), entire
mitochondrial genomes (Lang et al., 2002), and concatenated protein -
coding genes (Steenkamp et al., 2006).
Mitochondrial sequences included eight protein -
coding genes (COB, COI, COII, COIII, ND2, ND3, ND4, ND4L) and two RNA
genes (12S rRNA, 16S rRNA).
In fact, during the long course of evolution, this gradual transfer of genetic information into the nucleus has already occurred with the majority of
mitochondrial genome, leaving behind a mere 13 protein
coding genes within the mitochondria.
