Question

cells bacteria) do not contain the F plasmid. Position the In E. coli, F cells (male bacteria) contain the F plasmid, whereas F labels below with the correct images of conjugation in E. coli. After conjugation, both cells are F and can conjugate with F" cells. One strand of the plasmid passes through the pilus and into the female cell An F pilus produced by the male cell contacts and binds to the cell wall of a female cell. The pilus retracts and draws the F and F cells closer together. Có Reset Zoom

Answer 1

an F pilus is produced by the male cell contacts and binds to the cell wall of the female cell. The pilus retracts and draws the F+ and F- cells together. After conjugation both cells are F+ and can conjugate with F- cells. one strand of the F+ plasmid passes through the pilus and into the female cell. Reset Zoom

. F pilus us a hollow tubular outgrowth. & stands for patility. Bacteria can't show sexcull reproduction. But, they mimic sexual reproduction, by exchange of genetic material in between them The bacteria which contains an f plasmid us f the (male) while the bacteria which doesn't have f plasmid us f- female). The + strain replicates its & plasmid and donates one copy to the – strain minicing sercual reproduction (Just like a male donates genetic material in sperm to egg of female) . This type of exchange of genetic material 6/0 bacteria is called consugation. absolutely Plasmid neccessary us for extra chromosomal DNA. It surninal but consers special is not propertie to bacteria f bacteria Ft. It bacterial - after reciening the f plasmid can now further conjugate with to make it ft. becomes. other f- The donation & F plasmid occurs through the Epilus.

which is an attaches inbath outgrowth from the (Ft) male body and to the (F-) semale bacteria.
