A Sex Pilus Forms Duringــــــــــــــــــــــ

Question

A sex pilus forms duringــــــــــــــــــــــ .
A)transduction
B)conjugation
C)transformation
D)transfection

Accepted Answer

A sex pilus is a tubular appendage that is used in bacterial conjugation, a process where genetic material is transferred from one bacterium to another. During this process, the donor bacterium produces a sex pilus that attaches to the recipient bacterium, and the two bacteria exchange genetic material through a conjugation bridge that is formed by the sex pilus. Transduction, transformation, and transfection are other mechanisms of genetic exchange in bacteria, but do not involve the formation of a sex pilus.
