Choose the event below that does not occur during bacterial conjugation. Multiple Choice The recipient cell becomes a donor cell after conjugation. Enzymes cleave one strand of the DNA at the origin of transfer. Transfer of the DNA strands occurs in both directions. Shortening of the pilus occurs during conjugation. Direct contact between is made between donor and recipient cells.

The event that DOESN'T occur during bacterial conjugation is (Transfer of the DNA strands occurs in both directions)

Explanation:

Bacterial Conjugation can be defined as the type of sexual reproduction that can take place in bacteria in which genetic materials are being moved from a bacteria donor cell to a recipient through a DIRECT contact. The bacteria cells which act as donors contain DNA called the fertility factor ( F factor).

The detailed stages of conjugation which occurs in bacteria includes:

--> A direct contact is first established between the donor cell and the recipient cell through the use of a structure called the pilus. This structure is projects out from the donor cell.

--> the pilus shortens and a direct contact established between the two bacteria leads to formation of conjugation tube.

--> At the Origin of transfer site, an enzyme known as the HELICASE cleaves one strand of the F factor DNA. A strand is transferred to the recipient bacterial cell.

--> In the last step, the donor cell and the recipient cell, both contains single-stranded DNA of F - factor. Therefore, the recipient cell also contain a copy of F-factor and become a donor cell.

The option which says that transfer of DNA strands occurs in both directions is wrong because from the steps listed above, one strand of the F-factor DNA is transferred from a donor bacterial cell to a recipient, that is, unidirectional transfer of DNA and not in both directions.
