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.
Polio was nearly eradicated when society decided to mass produce and use a vaccine created by Jonas Salk. Polio was a big issue but they managed to cure it with a vaccine. Comments.
The 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.f course, that didn't stop inventor Dr. Jonas Salk from keeping busy â his last years were spent searching for a vaccine to combat AIDS.
