B
Transformation
C
Conjugation
D
Transduction
검증된 단계별 안내1
Understand the context: The problem is asking about a process in bacteria where DNA is transferred directly from one bacterium to another.
Identify the key term: The term 'pilus' is crucial here. A pilus is a hair-like appendage found on the surface of many bacteria.
Recall the process: Conjugation is the process where a pilus is used to transfer DNA directly between bacteria. This is different from other processes like transformation and transduction.
Differentiate the processes: Binary fission is a form of asexual reproduction, transformation involves uptake of DNA from the environment, and transduction involves DNA transfer via a virus.
Conclude with the correct process: Based on the use of a pilus for direct DNA transfer, the correct process is conjugation.
