To do that with DNA, we need to tell the DNA what to replicate, and then give it the means to do so. We do this by using enzymes and primers. Primers are a subject for another time, but they are responsible for telling the polymerase where to do its work.

Inventor of the Polio Vaccine. While there is still no actual cure for Polio, thanks to inventor Dr. Jonas Salk there is a way to prevent it. Before Salk invented the vaccine for Polio, America was forced to live in fear of the infectious viral disease that put Franklin Roosevelt in a wheelchair.he impact was dramatic: in 1955 there were 28,985 cases of polio in the U.S. and by 1957 that number had decreased to 5,894. Since he wanted it to be distributed freely to everyone, Dr. Jonas Salk never patented his polio vaccine.
