Molecular biology technologists perform laboratory procedures involving nucleic acids, biomarkers, and gene expression. They use PCR, electrophoresis, sequencing instruments, and molecular detection technologies to support clinical diagnostics, pathogen identification, oncology testing, and research studies. They work in hospitals, molecular labs, biotech firms, and academic institutions. With increasing reliance on molecular diagnostics for precision medicine and infectious-disease surveillance, demand for skilled technologists continues to grow. The role requires strong technical accuracy, analytical thinking, and adherence to laboratory quality and safety standards.
