Bacteria don't have epigenetic variation. They don't have histones which are proteins aroung which DNA forms 2 loops.
Bacteria have no introns no pre-RNA splicing. Bacteria have almost no non-coding DNA. You can have a look to the wikipedia page as well, you'll get more information. Was this page helpful? Thanks for your feedback! Sign Up. What are your concerns?

By way of analogy, two different recipes in an English language cookbook may use the same 26 letters to make words but differ in the exact sequence of those same 26 letters, resulting in different recipes. It is the order of bases that provides the instructions to produce, say, insulin in human pancreatic cells or photosynthetic enzymes in plants.
In any organism, such as a given human, the DNA in every cell has the same base sequence as every other living cell in that human.
Other genes remain present, but are not expressed. Meanwhile, skin cells express the genes unique to skin proteins, but liver and other genes are silenced. The language of genetics is the same in all of life. A gene from any cell of any living thing can be copied, transferred and understood by any other living thing to make the same protein. For example, human insulin is now made by microbes genetically engineered with the human DNA recipe for human insulin.
That is, a copy of the human insulin gene is transferred to microbes, and those microbes read the human insulin gene recipe and make insulin, even though the microbes — having no blood or blood sugar — have no use for insulin. Similarly, most hard cheeses now are made with chymosin a milk clotting enzyme generated by genetically modified microbes. From a scientific perspective, we can confidently state that life began at least once, about 3.
Answer: unlikely. The evidence is based on DNA being the sole common feature of all living things. More importantly, the language DNA uses to convey information is common to all; the same language is read and understood by all living things.
And most importantly, the DNA language is not just the common language used by all species; it is the only language used by any species. When considering the number of potential languages DNA might have used instead, the fact that all known life forms use the same language of DNA to communicate the same information is compelling evidence that life arose only once.
The fact that all living things use DNA as their physical hardware, and share a single language of DNA as their intellectual software, is evidence that all living things derive from a common ancestor way back when. Bacteria are not immune to viral hijackers which are known as bacteriophages —viruses that infect bacteria.
