How Does Molecular Biology Enhance Epidemiological Research?
Molecular biology provides tools such as PCR (Polymerase Chain Reaction), DNA sequencing, and gel electrophoresis to detect and analyze genetic material. These techniques help epidemiologists identify specific pathogens, understand their genetic variations, and track their transmission patterns. For example, during the COVID-19 pandemic, molecular techniques were crucial for detecting SARS-CoV-2, identifying its variants, and studying its spread.
