Description THE MYSTERY OF DNA REPLICATION 3 MacLeod, had been a member of a group of scientists that had shown that DNA could permanently change the inherited characteristics of the pneumococcus. However, most scientists, including some of my prelim committee, believed that only proteins were diverse enough to be responsible for the wide range of phenotypes (physical and chemical characteristics) that cells inherited and displayed. Another aspect of microbiology that I was expected to know was the adaptive response of microorganisms. A great deal of study begun by Marjorie Stephenson and continued by Ernest Gale in England had shown that the characteristics of bacterial PROTEIN COAT Contains many different proteins. \ (Ol PROTEIN <? SUBUNIT I HEAT <2^ 1. Phage. Phage, or bacteriophage, is a virus that attacks bacteria. The best known are the ones which attack the bacterium E. coli. These were studied by Delbriick and other scientists of the phage group. The virus consists of a DNA core surrounded by a protein coat. DNA is a double helix made up of two strands of sugars linked together. Attached to these are bases which pair with each other giving rise to the complementary nature of the two strands. The protein coat consists of many different protein molecules which, if heated, unfold to give long strings of subunits (peptide chains) in which the backbone consists of carbon and nitrogen atoms. In 1953 Al Hershey and Martha Chase demonstrated that even though only the DNA of a phage had entered the bacterium, phage proteins were made. This demonstrated that DNA carried the information for making phage protein. DNA CORE PHAGE
