Please read this file explanation on syncopation and natural ratios. This is a guide to understanding cellular and atomic growth through division. The growth is a function of groups through combinations of partial atoms. (2, 8, 18, 32)
This explains why Mitochondria still exist, as they are DNA instructions lead out through amplification over time. The cell builds around the magnetic instructional format of the DNA. What you see is an enlarged version of the DNA strand itself.
This continues until whole organs are made.
The first biological entities which were formed as a result of mitochondria are a result of our systems 3rd ratios where 1 became 2, became 8, became 18, became 32 until the mitochondria became an inside function of the new organism, where it was itself the new blueprint. This happened over and over again as a matter of subdivides spawning more and more new DNA instructions.
