Question

F plasmid is often used in conjugation. The correct statement is?

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

(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 same species to carry out the conjugation

This question was addressed to me in an interview for internship.

I need to ask this question from Transformation topic in chapter Basics of Genetic Engineering of Genetic Engineering

Answer 1

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

The best explanation: 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.
