The evidence that one strain of bacteria can often transform another strain suggests that bacteria
A) are able to change into viruses.
B) must have protein as their hereditary material.
C) might be able to exchange pieces of DNA encoding antibiotic resistance.
D) must have single-stranded DNA in order to undergo transformation.

Question

Quizplus · Accepted Answer

The ability of one strain of bacteria to transform another suggests that bacteria can exchange genetic material, which could include pieces of DNA encoding antibiotic resistance. This has important implications for the spread of antibiotic resistance among bacterial populations. A and D are incorrect as they are not supported by the evidence provided. B is also incorrect as bacteria can have other types of hereditary material beyond just protein.
