Question

a scientist puts two bacteria in the same test tube. one of them can survive penicillin, but the other cant. the next day, the bacteria are tested and now both can survive penicillin. which method of dna transfer that involves a long, thin tube would create this result? conjugation transformation transduction

Explanation:

Conjugation is a method of DNA - transfer in bacteria that involves a long, thin structure called a pilus which acts like a tube to transfer genetic material from a donor bacterium to a recipient bacterium. In this case, the bacterium with penicillin - resistance likely transferred its resistant gene to the non - resistant one via conjugation. Transformation involves the uptake of free DNA from the environment, and transduction involves the transfer of DNA by a virus.

Answer:

conjugation
