Bacteriophages Can Be Used as Vectors in Recombinant DNA Experiments

Question

Bacteriophages can be used as vectors in recombinant DNA experiments because they
A) are small and made of double-stranded DNA.
B) are circular and easily imported into bacteria or yeast.
C) insert their genetic material into bacteria.
D) are resistant to protective restriction systems.
E) infect human and other animal cells.

Accepted Answer

Bacteriophages insert their genetic material into bacteria, making them useful as vectors in recombinant DNA experiments. Option A is incorrect because not all bacteriophages are made of double-stranded DNA. Option B is incorrect because not all bacteriophages are circular and can be easily imported into bacteria or yeast. Option D is partially correct because bacteriophages can be resistant to protective restriction systems but this alone does not make them appropriate vectors for recombinant DNA experiments. Option E is incorrect because bacteriophages do not infect human or other animal cells but rather infect bacteria.
