Bacterial DNA, or bacteria DNA, have a resemblance to human DNA in that the DNA of either is double-helical. There is a difference also; the bacteria’s DNA is formed of plasmids, which would be circular in their double stranded DNA composition while the human DNA holds a linear form.
The DNA of any organism holds the code for the internal development and function of that organism. DNA is furthermore separated into various components, which include genes, yet other parts of the DNA serve as regulators of the genetic information. DNA is a macromolecule and is pertinent to all life for survival, along with protein and RNA. The DNA hold two chains or polymer units of nucleotides that have as their spine sugars and then extend with ester bonds that join the phosphate groups of the molecule. The nucleotide strands or chains move in opposite directions in such the way that they are anti-parallel.
The DNA of a bacteria uses the sugars in its spine for carrying its nucleobases. The nucleobases are stationed in a particular sequence. It is this sequence of the nucleobases that encodes information for the cell. This sequence of four nucleobase types works for each DNA for every organism that exists with the exception of one group of organisms that only have an RNA to work with, the RNA viruses. During virus transcription the RNA receives the DNA’s information about the sequence of the amino acids within the protein of the cell that holds that particular DNA. RNA, just like DNA is a nucleic acid and these two components of a cell transfer or transcribe through the actions of specific enzymes.

The DNA’s transcription encoding includes the sequence information needed for a particular cell as well as the regulating information that will serve to direct the proteins’ synthesis. A transcription will always encode at least one gene. DNA replication occurs in every living organism. DNA replication is the process at which a bacteria or any organism copies their own DNA. This process of copying the DNA within itself is biological. At the beginning of the DNA there is an occurrence of unwinding, a synthesis of newly formed strands and these newly formed strands take the form of a replication fork. Even more proteins join the replication fork and aid in the completion of the DNA synthesis.
DNA replications can even be accomplished outside of the given cell. By using artificial synthesis or the polymerase chain reaction laboratory method. Many interesting things have been discovered about different bacterium and their DNA. It has even been discovered that there are bacteria with DNA maps that can produce arsenic.
