Question

Which characteristic is imparted by F-plasmids to host bacterium?

Answer

A. Antibiotic resistance

B.

C.

D.

Fluorescent colonies

Conjugative ability

Virulence​

Answer 1

Explanation:

T4 can be used in higher organisms and has a lysogenic life cycle and hence a vector of choice. 9. Which characteristics do F-plasmids confer to the host bacterium? Explanation: F-plasmids or fertility plasmids are responsible for providing a conjugative ability to the bacterium.

Answer 2

Answer:

Characteristic imparted by F-plasmids to host bacterium is conjugative ability.

Explanation:

The F-plasmid is also known as the F factor or F sex factor as it is the sex factor in E.coli. It is the fertility factor that allows gene transfer from one bacterium to another bacterium lacking the factor by conjugation. The first plasmid discovered is this F plasmid. This belongs to a group of plasmids that control the sexual functions of the bacteria with a fertility inhibition system.

The functional segments of the F factor are;

• OriT (origin of transfer)
• OriV (origin of vegetative replication)]
• tra-Region (transfer genes)
• IS (insertion elements)
