Question

which form of dna transfer between bacterial cells involves a bacteriophage (bacterial virus)?
transformation
conjugation
mutation
transduction

Explanation:

Transformation is the uptake of free DNA from the environment. Conjugation involves direct cell - to - cell contact through a pilus. Mutation is a change in the DNA sequence within a cell. Transduction is the process where a bacteriophage (bacterial virus) transfers DNA from one bacterial cell (donor) to another (recipient). As shown in the diagram, phages carrying donor genes are involved in the transfer, which is characteristic of transduction.

Answer:

transduction
