Document Summary
Dna replication how a molecule of dna is copied. The search for the genetic material: scienti c inquiry. Frederick gri th was conducting experiments in which he tried to develop a vaccine against pneumonia . During his experiments, he discovered the phenomenon transformation a change in genotype and phenotype due to the assimilation of of external dna by a cell. Additional evidence that dna was the genetic material came from the studio of viruses that infect bacteria . Virus is little more than dna (or sometimes rna) enclosed by a protective coat. Alfred hershey and martha chase conducted an experiment . They found that th phage dna entered the host cells but the phage protein did not. They concluded that the dna injected by the phage must be the molecule carrying the genetic information that makes the cells produce new viral dna and proteins.
