Microbes can thrive in a variety of environments, extreme environments as well normal soil and water where most the other species are found. The ability to adapt various habitats confirms why bacteria, especially prokaryotes, abundant organisms on earth.

Although genes in prokaryotes and eukaryotes are transcribed and translated by very different mechanisms, they may be organized in their respective chromosomes in surprisingly similar ways. Here, I examine common modes of maintaining nonrandom gene organization in both prokaryotes and eukaryotes, the different ways these organizations have likely arisen, and classes of organization that may be ...

We studied the evolution of thermophily in prokaryotes using the phylogenetic relationships between 279 bacteria and archaea and their thermophilic amino acid composition signature. Our findings suggest several examples in which the capacity of thermophilic adaptation has been gained or lost over relatively short evolutionary periods throughout the evolution of prokaryotes.

The differences in the biochemistry of messenger RNA formation in eukaryotes compared to prokaryotes are so profound as to suggest that sequential prokaryotic to eukaryotic cell evolution seems unlikely. The recently discovered noncontiguous sequences in eukaryotic DNA that encode messenger RNA may reflect an ancient, rather than a new, distribution of information in DNA and that eukaryotes evo...

BACKGROUND The 16s rRNA gene is so far the most widely used marker for taxonomical classification and separation of prokaryotes. Since it is universally conserved among prokaryotes, it is possible to use this gene to classify a broad range of prokaryotic organisms. At the same time, it has often been noted that the 16s rRNA gene is too conserved to separate between prokaryotes at finer taxonomi...
