What does the term "transfection" refer to?

• A. The process of screening for mutations
• B. The introduction of nucleic acids into cells
• C. Injecting chemicals into plant cells
• D. Measuring gene expression levels

Answer: (B)

Transfection specifically refers to the introduction of nucleic acids—such as DNA or RNA—into cells. This process is crucial in molecular biology and biotechnology as it enables scientists to manipulate gene expression, study gene function, or produce recombinant proteins. Transfection can be achieved through various techniques, including chemical methods, electroporation, and viral methods, depending on the type of cells being targeted and the desired outcome. The other options do not encapsulate the definition of transfection. While screening for mutations focuses more on identifying changes in genetic material, and injecting chemicals into plant cells typically refers to different methodologies like biolistics or Agrobacterium-mediated transformation, measuring gene expression levels pertains to techniques used after nucleic acids have been successfully introduced to assess the outcome of that introduction. Therefore, the emphasis on introducing nucleic acids into cells accurately captures the essence of transfection.
