Transcriptomics is a way to study all the genes that are active in cells or tissues at a given time. Think of it like taking a snapshot of which genes are "turned on" in a cell. Researchers use this to understand diseases, drug responses, and how organisms develop. It's similar to looking at all the recipes (genes) being used in a kitchen (cell) at once. This field is part of the broader genomics area, alongside techniques like genomics (studying all genes) and proteomics (studying all proteins). When you see this term in resumes, it usually indicates experience with analyzing gene activity data using specialized laboratory and computer methods.
