Lecture Objectives After this lecture, students will be able to: Describe the DNA types in bacteria and the consequences of homologous recombination. Describe the steps and outcomes of bacterial transformation, conjugation, and transduction. Discuss transposons and integrons, how they cause mutations and contribute to the spread of antibiotic resistance genes. Compare genetic drift and shift and discuss the mechanisms by which they occur inviruses. Describe phenotypic mixing and masking and the outcome of infection with a composite virus.

The type of DNA in most of the bacteria contained in a singular circular molecule and its called bacterial chromosome.These chromosomes along with protiens and RNA molecules results improper shaped structure called nucleoid.In bacteria cell it situated in cytoplasm.
Recombination generally happens when two molecules of DNA exchange their genetic material with each other.Nucleotide sequences are exchanged between two identical molecules of DNA is known as Homologous recombination.It takes a very crucial role to repair DNA process in bacteria.
In bacteria it results gene transfer to exchange genetic material between different species.
