Gene Expression
Gene Expression is a fundamental process that scientists study to understand how genes work in living things. Think of it like reading instructions from a cookbook (DNA) to make specific proteins that cells need. Researchers who work with gene expression study how these instructions are turned on or off, which helps develop new medicines and treatments. This is similar to studying which light switches control which lights in a building. Scientists use various methods like RNA sequencing and microarrays to measure gene expression. You might see this term used alongside "transcriptomics" or "molecular biology" in job descriptions.

Example Interview Questions
Senior Level Questions
Q: How would you design a gene expression study for a new drug's effects?
Expected Answer: A senior scientist should explain the process of experimental design, including controls, replicates, choosing appropriate methods for measuring gene expression, and statistical analysis approaches. They should emphasize the importance of validation and reproducibility.
Q: How do you handle large-scale gene expression data analysis?
Expected Answer: Should discuss experience with managing big datasets, quality control measures, statistical methods, and how to interpret and present complex results in a meaningful way to different audiences, including non-technical stakeholders.
Mid Level Questions
Q: What methods do you use to validate gene expression results?
Expected Answer: Should describe different validation techniques like RT-PCR, explain why validation is important, and demonstrate understanding of when to use different validation methods.
Q: How do you troubleshoot failed gene expression experiments?
Expected Answer: Should explain systematic approach to problem-solving, including checking sample quality, reviewing protocols, and implementing controls. Should demonstrate experience with common technical issues.
Junior Level Questions
Q: What are the basic steps in measuring gene expression?
Expected Answer: Should be able to explain the simple workflow of RNA extraction, quality checking, and basic measurement techniques. Should understand laboratory safety and documentation requirements.
Q: How do you maintain sample quality for gene expression analysis?
Expected Answer: Should know basic sample handling procedures, storage requirements, and contamination prevention measures. Should understand the importance of proper documentation.
