WebGenetic Exchange Between Bacteria. Part of the genetic material of a donor cell can be transferred to a recipient cell. After the transfer, recombination between the donor and recipient DNA may occur followed by succeeding nuclear and cell division. The model for recombination is as follows: Homologous DNA strands pair. WebFeb 2, 2008 · Bacteria can go through a phase in which two bacteria exchange genetic material with one another by passing pieces of DNA across a bridge-like connection. Lederberg also proved the phenomenon known as transduction, in which DNA is transferred between bacteria via bacteriophages.
