Prokaryotic Gene Regulation – Biology

WebThere are three mechanisms by which prokaryotes can exchange DNA. In (a) transformation, the cell takes up prokaryotic DNA directly from the environment. The DNA may remain separate as plasmid DNA or be incorporated into the host genome. In (b) transduction, a bacteriophage injects DNA into the cell that contains a small fragment of … WebThe prokaryote, now enlarged, is pinched inward at its equator and the two resulting cells, which are clones, separate.
