So this is the recipient. It doesn't actually contain our f plasmid initially, but after the f plasmid is transferred, now this recipient becomes a donor, and it can basically go on and transfer the f plasma to other recipient cells. Now, the f plasmid, our fertility factor, is not the only plasma that exists. There are other plasmids that exist, such as, for example, the rplasmid. The rplasmid is basically a plasmid that not only contains the proteins that code for the sex pillars, it also contains proteins that give our cell resistance to drugs and antibiotics. So basically, this process is known as mating because we have two individual cells that basically interact via this cytoplasmic bridge known as the sex pillars, and we transfer genetic information from the donor to our recipient in this process of genetic recombination in bacterial cells is known as conjugation.
