In Tube 2 they add 32P labeled bacteriophage and E. coli bacteria. They blend it up to remove the bacteriophage coats and separate the coat from the cells using a centrifuge. The radioactive phosphorus (32P) appeared inside the cells. None of the radioactive sulfur (35S) appeared in the cells. ]]> 2021-03-02 14:53:29 UTC https://padlet.com/lesliecampbell21/83gnid6v7fim49xg/wish/1258678491 https://padlet.com/lesliecampbell21/83gnid6v7fim49xg/wish/1258688341 Chargaff separated the purine bases and the pyrimidine bases using paper chromatography. He then determined how much of each base there was for several different organisms. ]]> 2021-03-02 14:54:53 UTC https://padlet.com/lesliecampbell21/83gnid6v7fim49xg/wish/1258688341 https://padlet.com/lesliecampbell21/83gnid6v7fim49xg/wish/1258756758 James Watson and Francis Crick wanted to determine the 3-dimensional structure of DNA. He generated DNA crystals and shot x-rays to study his structure, the x-ray picture showed a repeated pattern which meant to be something similar to a helix.
