Genetic change in bacteria can be brought about by which of the following processes?
A
Direct cell division without DNA exchange
B
Synthesis of new proteins without genetic alteration
C
Loss of plasmids during replication
D
Uptake of foreign DNA from the environment (transformation)
Verified step by step guidance1
Understand that genetic change in bacteria involves alteration or acquisition of new genetic material, which can lead to variation in traits.
Recognize that direct cell division without DNA exchange (binary fission) produces genetically identical daughter cells, so it does not cause genetic change.
Note that synthesis of new proteins without genetic alteration does not change the DNA sequence, so it does not represent a genetic change.
Consider that loss of plasmids during replication results in loss of genetic material but is not a process of acquiring new genetic information.
Identify that uptake of foreign DNA from the environment, known as transformation, introduces new genetic material into the bacterial genome, causing genetic change.
