Bacterial genetics is the subfield of genetics devoted to the study of bacterial genes. Bacterial genetics are subtly different from eukaryotic genetics, however bacteria still serve as a good model for animal genetic studies. One of the major distinctions between bacterial and eukaryotic genetics stems from the bacteria's lack of membrane ...
In bacteria, however, the strong correlation between the number of genes and the genome size makes the size of bacterial genomes an interesting topic for research and discussion. [ 11 ] The general trends of bacterial evolution indicate that bacteria started as free-living organisms.
Bacteria are classified by their shape. Bacteria have been on this planet for approximately 3.5 billion years, and are classified by their shape. [9] Bacterial genetics studies the mechanisms of their heritable information, their chromosomes, plasmids, transposons, and phages.
This list of sequenced eubacterial genomes contains most of the eubacteria known to have publicly available complete genome sequences.Most of these sequences have been placed in the International Nucleotide Sequence Database Collaboration, a public database which can be searched [1] on the web.

Transduction This is an illustration of the difference between generalized transduction, which is the process of transferring any bacterial gene to a second bacterium through a bacteriophage and specialized transduction, which is the process of moving restricted bacterial genes to a recipient bacterium. While generalized transduction can occur ...
In contrast, bacteria also import genes in a process called homologous recombination, first discovered by the observation of mosaic genes at loci encoding antibiotic resistance. [11] The discovery of homologous recombination has made an impact on the understanding of bacterial evolution.
Bacterial transcription is the process in which a segment of bacterial DNA is copied into a newly synthesized strand of messenger RNA (mRNA) with use of the enzyme RNA polymerase. The process occurs in three main steps: initiation, elongation, and termination; and the result is a strand of mRNA that is complementary to a single strand of DNA.
