Discovery: Discovered  transformation by injecting mice with heat killed bacteria.]]> 2020-02-25 16:40:40 UTC https://padlet.com/8107161/h7xem2wfpf87/wish/450206502 Avery, McCarty, MacLeod 837506 https://padlet.com/8107161/h7xem2wfpf87/wish/450209680 Date: 1944
Discovery: Transformation caused by DNA, not proteins
Method: Treated heat killed bacteria with enzymes]]> 2020-02-25 16:43:57 UTC https://padlet.com/8107161/h7xem2wfpf87/wish/450209680 Chargaff 837506 https://padlet.com/8107161/h7xem2wfpf87/wish/450212016 Date: 1950
Discovery: Amount of nitrogen bases are consistent (A=T, C=G)
Method: Biochemical analysis and chromatography]]> 2020-02-25 16:46:39 UTC https://padlet.com/8107161/h7xem2wfpf87/wish/450212016 8107161 https://padlet.com/8107161/h7xem2wfpf87/wish/450212971 Scroll down on picture to view info]]> 2020-02-25 16:47:47 UTC https://padlet.com/8107161/h7xem2wfpf87/wish/450212971 Hershey/Chase 837506 https://padlet.com/8107161/h7xem2wfpf87/wish/450213337 Date: 1952
