  • Basic structure of DNA was known

  • Period: to

    Linus Pauling

    Shows that polypeptide chains are often held in the shape of an a-helix by hydrogen bonds that could be broken by heating. Suggested that this could relate to changes seen in DNA on heating
  • Period: to

    Oswald Avery, Colin MacLeod, Maclyn McCarty

    Showed DNA was the material of inheritance.
  • Erwin Chargaff finds that proportions of C-G are the same and T-A are the same and that there are no relationships between other combinations of bases.
