Bookmark or Share- Bacteria - Genetic Content, DNA, Prokaryotes | BritannicaThe sequence of bases in the DNA has been determined for hundreds of bacteria. The amount of DNA in bacterial chromosomes ranges from 580,000 base pairs in Mycoplasma genitalium to 4,700,000 base pairs in E. coli to roughly 9,450,000 base pairs in Myxococcus xanthus.
- Genetics - Medical Microbiology - NCBI BookshelfThe genetic material of bacteria and plasmids is DNA. Bacterial viruses (bacteriophages or phages) have DNA or RNA as genetic material. The two essential functions of genetic material are replication and expression.
- The Divided Bacterial Genome: Structure, Function, and EvolutionApproximately 10% of bacterial genomes are split between two or more large DNA fragments, a genome architecture referred to as a multipartite genome.
- Bacterial DNA – the role of plasmids — Science Learning HubThe DNA of most bacteria is contained in a single circular molecule, called the bacterial chromosome. The chromosome, along with several proteins and RNA molecules, forms an irregularly shaped structure called the nucleoid.
- 8.5: Structure and Organization of DNA in BacteriaWe will close this chapter with a look at sex (E. coli style!), and gene-mapping experiments showing linearly arranged genes on a circular bacterial DNA molecule (the bacterial ‘chromosome’). E. coli sex begins when F+ and F- cells meet. These cells are “opposite” mating types that can share DNA during conjugation.
