Nitrogen fixing has been more fully explored in ”Fixations: Nitrogen, Legumes, Fruit & Vegetables, Unity Consciousness #979” Another role of prokaryotes is to transform and compose elements and compounds. Prokaryotes are among the organisms essential to the binding of nitrogen into a gaseous form that allows nitrogen to be removed from the soil.
Gene Expression Affects How Cells FunctionPart 1 of 2 identifies the on/off switching mechanism of genetic material as one of the basic reasons human cells function differently. If this is accurate, then it must also hold true for prokaryotes.
A brief review of the distinctions made between the prokaryotes. Archaea and Bacteria, verifies this conclusion.
Differences in function are caused by differences in gene expression which is caused by differences in which genes are turned on and off.
This is just how a computer's binary code operates by representing a series of on and off switches that determines how a computer functions. Gene expression is computer code expression. We are all clones of the same code in different sized configurations. Once again we have verification, cells are computers and so are we. In prokaryotes the default state of gene expression is on. In organisms such as plants and humans, our default gene expression for protein synthesis is off. I suspect this has something to do with the lifespan of organisms. The shorter the lifespan, the more continuous protein synthesis must be because there is no time to be waiting around for a catalyst to turn on what's needed. A default “on” state saves time and energy.
