BACTERIOLOGY CHECKPOINT

The most basic taxonomic group consisting of collection of bacterial strains

Bacteria contains both DNA and RNA

Sedimentation coefficient of prokaryotes

Contain set of genes essential for viability, growth and replication of microorganisms

Composed of genes for movement as well as genes that code for other features such as drug resistance

Codes for antibiotic resistance, virulence and toxin production

Refers to all set of genes

Plasmid is a non-chromosomal double stranded DNA which is not capable of self-replication Transposable elements consists of insertion sequence and transposons

Pieces of elements that move from one genetic element to another

Function: selective permeability, transport and excretion
