Question

Which best describes the different modes of bacterial reproduction?

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.

Answer 1

B is the correct answer

Answer 2

Answer;

B. In conjugation, a special sex pilus is required to connect two bacterial cells.

Explanation;

-Bacteria reproduce through a process called binary fission. During binary fission, the chromosome copies itself, forming two genetically identical copies. Then, the cell enlarges and divides into two new daughter cells.

-In conjugation, DNA passes through an extension on the surface of one bacterium and travels to another bacterium. Bacteria essential exchange DNA via conjugation.

In transformation, bacteria pick up pieces of DNA from their environment. While in transduction, viruses that infect bacteria carry DNA from one bacterium to another.
