what tools does a geneticist use
Someone may be exposed to a virus one day and then bring it back to their own city the next. Cities are growing bigger and denser, and we're gathering in large crowds at sport and other events. Fortunately, today scientists can use genetic tools, such as DNA sequencing, to learn about new strains of viruses. These tools are helping researchers identify the cause of an infection, piece together a story about where new viruses come from, diagnose new cases, and develop preventive vaccines.
