(b) The factor encoded by the F plasmid is called as Filamentous (F) factor

(c) It is transferred from one cell to another by filament

(d) The bacteria must belong to the same species to carry out the conjugation

This question was posed to me in an international level competition.

Answer 1

Right answer is (a) The F plasmid encodes the factor which is transferred from one cell to another

To explain: F plasmid encodes the factor called Fertility or F factor. It is transferred from one cell to another by the sex pilus. It is present in E. coli and for the conjugation to take place; bacteria can also belong to different species.
