Chase biology
WebThe Hershey-Chase experiments. In their now-legendary experiments, Hershey and Chase studied bacteriophage, or viruses that attack bacteria. The phages they used were simple particles composed of protein and DNA, with the outer structures made of protein and the inner core consisting of DNA. WebIn fact, until the 1950s, the structure of DNA remained a mystery. In this article, we'll briefly explore how the double-helical structure of DNA was discovered through the work of James Watson, Francis Crick, Rosalind Franklin, and other researchers. Then, we'll take a look at the properties of the double helix itself.

Today, we know that DNA is the genetic material: the molecule that bears genes, is passed from parents to children, and provides instructions for the growth and functioning of living organisms. But scientists didn’t always know this.
The Hershey–Chase experiments were a series of experiments conducted in 1952 by Alfred Hershey and Martha Chase that helped to confirm that DNA is genetic material. While DNA had been known to biologists since 1869, many scientists still assumed at the time that proteins carried the information for inheritance becau… WebLearn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more.
