Question

Sex factor in bacteria is

• A. F- pilus
• B. Chromosomal replicon
• C. RNA
• D. None of above

Answer 1

The correct option is A F- pilus

The bacterial cells are of two types, F${}^{+}$ and F${}^{-}$. The F${}^{+}$ cell possesses a circular plasmid containing the gene called as the sex factor. This sex factor is responsible for the growth of F-pili which is involved in the process of conjugation where the lateral transfer of genes takes place.

Thus, the correct answer is option A.
