Conjugation and Plasmids In a process called conjugation, genetic material is transferred between two bacterial cells (of same or different species) that are temporarily joined. The DNA transfer is one way: One cell donates the DNA,a nd the other receives ti.The donor uses sex pili to attach to the recipient.he cell is now a recombinant: Its chromosome contains DNA derived from two different cells. In transduction, bacteriophage carry bacterial genes from one hose cell to another; transduction is a type of horizontal gene transfer.
