Question 7 • TPS EdX Biology

Fast reproduction by binary fission enables bacteria to

Answer
A
quickly modify their DNA to changing conditions.
B
change shape from coccus to bacillus.
C
transfer DNA from one cell to another.
D
cause infections in other organisms.

Explanation

Binary fission allows bacteria to reproduce quickly, increasing their population in a short time. A large, rapidly growing population can make it easier for bacteria to establish an infection in another organism. Binary fission does not itself transfer DNA between cells or change a bacterium’s shape.
