WebSo bacteria acquire genetic variation through random mutation, but, unlike humans or oak trees, they also regularly get new gene variants through the process of horizontal transfer — that is, they can pass DNA back and forth to one another directly. WebStill, genetic variation is key to the survival of a species, allowing groups to adapt to changes in their environment by natural selection. That's true for bacteria as well as plants and animals.

WebKey points: Viruses undergo evolution and natural selection, just like cell-based life, and most of them evolve rapidly. When two viruses infect a cell at the same time, they may swap genetic material to make new, "mixed" viruses with unique properties. For example, flu strains can arise this way. WebBacteria can take up foreign DNA in a process called transformation. Transformation is a key step in DNA cloning. It occurs after restriction digest and ligation and transfers newly made plasmids to bacteria. After transformation, bacteria are selected on antibiotic plates. WebNormally, the enzyme fucose isomerase is induced in these bacteria when some fucose enters the cell and binds to a positive regulatory protein, which then turns on the gene for the isomerase. The regulatory protein of some mutants, … damn near kilt them
