Modes of gene transfer in bacteria
Web5 apr. 2024 · Sexually reproducing organisms have two sets of chromosomes, one set from each parent, and therefore have two versions of each gene.This arrangement increases genetic diversity. However, bacteria have found ways to increase their genetic diversity through three recombination techniques: transduction, transformation and conjugation. WebDNA material can be transferred between different strains of bacteria in a process that is called horizontal gene transfer. Some species, upon cell death, release their DNA to be taken up by other cells; however, transformation …
