Bacteriophages have been used widely in genetic research since they are the smallest and simplest biological entities capable of what?
Correct answer: A. Self replication in host cell
- A. Self replication in host cell
- B. Duplication
- C. Self duplication
- D. Multiplication in host cell
Explanation
The most accurate answer is self-replication in a host cell, since bacteriophages can reproduce only by infecting bacteria and directing the host machinery to make copies of themselves. "Multiplication in host cell" is acceptable but less precise, while "self-duplication" and "duplication" are incorrect because they do not accurately describe viral replication.
