The Hershey and chase experiment conclusively proved that DNA was the genetic material. Alfred Hershey and his lab technician Martha Chase carried out this experiment. The discovery began when Alfred Hershey believed that proteins were more likely to carry genetic material than was the simple DNA molecule. They decided to track the transfer of protein DNA between a virus and its host by the T2 bacteriophage as the vehicle for delivering genetic material. To reproduce‚ the bacteriophage injects its

Prevention for Noonan Syndrome looks slightly different than other disorders‚ due to the fact that it is genetically linked. With cases of NS being linked to different genetics and some cases having an unknown origin‚ it is hard to prevent the disorder from occurring. A big factor towards prevention lies in the education of the people closest to the patient‚ the community‚ and the general public. A very effective preventive way would be to administer genetic testing to the population in order to
