Verified step by step guidance1
Step 1: Understand the definitions of each process listed. Transduction, transformation, and conjugation are all methods by which bacteria can acquire new DNA from external sources.
Step 2: Define transduction as the process where bacterial DNA is transferred from one bacterium to another by a virus (bacteriophage).
Step 3: Define transformation as the uptake of free DNA molecules directly from the environment into a bacterial cell.
Step 4: Define conjugation as the direct transfer of DNA between two bacterial cells through cell-to-cell contact, often involving a pilus.
Step 5: Recognize that translation is a process in molecular biology where messenger RNA (mRNA) is decoded to synthesize proteins, and it does not involve the introduction of DNA into bacterial cells.
