Example: </span>Mitochrondria of the eukaryotic cells.
As
many researchers hypothesize that the old single-celled organism or the
origin of the complex-celled organisms came from the endosymbiosis of
the mitochrondrion organism and the prokaryotic cell. It has been said
that mitochondria was an independent organism which then to have been
evovled itself after planting itself inside a prokaryotic cell which
aided cellular respiration and production of ATP (Adenosine
Triphosphate). This then aided the prokaryotic cell to be more
sophisticated and caused another change from having without a true
nucleus to a eukaryotic cell with a nucleus and embedded DNA. </span>
There should be 22% Thymine because of Thymine pairs with Adenine, which on the table is shown to be 22%. (the complementary base pair are always equal). and the same would apply to Guanine (28%) and cytosine (28%).
