RNA Extraction
RNA Extraction is a fundamental laboratory procedure used to isolate genetic material (specifically RNA) from biological samples like blood, tissue, or cells. Think of it like separating egg yolk from egg white, but at a microscopic level. This process is essential in genetic research, disease diagnosis, and drug development. Scientists use this technique to study how genes work, identify diseases, and develop new treatments. When you see this term in a resume, it indicates that the candidate has hands-on laboratory experience with genetic material handling.

Example Interview Questions
Senior Level Questions
Q: How would you troubleshoot poor RNA yield in extractions?
Expected Answer: A senior technician should explain systematic approach to problem-solving: checking reagent quality, sample storage conditions, protocol steps, and equipment calibration. They should mention experience training others and establishing quality control measures.
Q: How do you maintain quality control in RNA extraction procedures?
Expected Answer: Should discuss implementing standard operating procedures, documentation practices, proper sample tracking, and quality metrics like purity ratios and integrity checks. Should mention experience in developing and updating protocols.
Mid Level Questions
Q: What methods do you use to prevent RNA degradation during extraction?
Expected Answer: Should describe proper sample handling, use of RNase-free materials, proper storage conditions, and basic troubleshooting skills. Should show understanding of why these precautions are important.
Q: Explain how you document your RNA extraction procedures.
Expected Answer: Should discuss lab notebook maintenance, following standard operating procedures, recording important parameters, and tracking samples through the process.
Junior Level Questions
Q: What basic safety precautions do you take when performing RNA extractions?
Expected Answer: Should mention proper protective equipment (gloves, lab coat, eye protection), handling of chemicals, proper waste disposal, and following basic laboratory safety protocols.
Q: What are the basic steps in RNA extraction?
Expected Answer: Should be able to describe the general process: sample preparation, cell breaking, separation of RNA from other materials, and proper storage of extracted RNA.
