Recombinant DNA Technology

Disembarkation of the Spanish at Veracruz by Mexican artist Diego Rivera. Anthropologists have suggested that Europeans first transmitted tuberculosis to the Native Americans. The polymerase chain reaction—a technique for amplifying very small amounts of DNA—has now demonstrated the presence of the bacterium that causes tuberculosis in a 1000 year old mummy from Peru, demonstrating that the disease was present in South America long before Europeans arrived.
