Plasmids are passed on to other bacteria through two means. For most plasmid types, copies in the cytoplasm are passed on to daughter cells during binary fission. ... Other types of plasmids, however, form a tubelike structure at the surface called a pilus that passes copies of the plasmid to other bacteria during conjugation,

First, two bacteria combine via a sex pilus. Next, one strand of ... i) Pair formation - The tip of the sex pilus comes in contact with the recipient and a conjugation bridge is formed between the two cells. It is through this bridge that the DNA will pass from the donor to the recipient. ... Figure 11 R plasmid structure...

After several days, all of the bacteria are F+. A plasmid is exchanged between bacteria through a pilus. Movement of a sequence of DNA to alternative locations in the DNA. DNA is present that does not provide any known benefit to the cell, yet is replicated each time the genome replicates.
