Question 12 • FL-2000310-Biology 1 Sem 2

Which best describes the different modes of bacterial reproduction?

Answer
A
In genetic recombination, two new genetically identical cells are produced.
B
In conjugation, a special sex pilus is required to connect two bacterial cells.
C
In transduction, a bacterium exchanges a piece of its own DNA with another from the environment.
D
In transformation, bacterial DNA is transferred from one bacterium to another by a replicating virus.

Explanation

Conjugation is the transfer of DNA between bacterial cells through direct contact, typically using a special sex pilus to connect them. A describes binary fission, which produces genetically similar daughter cells, not genetic recombination. Transformation is uptake of DNA from the environment, while transduction is DNA transfer by a virus.
