How did scientists determine that DNA is the hereditary material? This groundbreaking discovery involved a series of experiments with bacteria and bacteriophages, or viruses that infect bacteria. The 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. The term nucleic acid is the overall name for DNA and RNA, members of a family of biopolymers, [11] and is synonymous with polynucleotide. Nucleic acids were named for their initial discovery within the nucleus, and for the presence of phosphate groups (related to phosphoric acid). [12] Although first discovered within the nucleus of eukaryotic ...Cool the mixture by placing the beaker in an ice-water bath for 5 min, stirring frequently. This slows the breakdown of the DNA that would occur if a high temperature were maintained. Filter the mixture into a second beaker. Ensure that any foam on top of the liquid does not contaminate the filtrate.
