Question 8 • TPS EdX Biology

Which correctly describes a process that occurs in bacteria?

Answer
A
In transduction, the cells that are formed are susceptible to the same antibiotic.
B
In conjugation, bacterial DNA is transferred from one bacterium to another by a replicating virus.
C
In binary fission, the two new cells that are formed are susceptible to the same antibiotic.
D
In transformation, a special sex pilus is required to connect two bacterial cells.

Explanation

In binary fission, one bacterial cell copies its DNA and divides into two daughter cells. Because the daughter cells usually have the same genetic information, they are generally susceptible to the same antibiotic. Transduction uses a virus to transfer DNA, conjugation uses direct cell-to-cell contact, and transformation involves taking up DNA from the environment.
