27 avr. 1949 - Erwin Chargaff
Description:
He used paper chromatography and UV spectrophotometry in his experiment. Chargaff drew the conclusion that it is in fact the DNA in the nucleus of the cell that carries genetic information rather than the protein. Chargaff discovered that the proportions of bases in DNA depend on the species the DNA comes from.Ajouté au bande de temps:
