Do proteins contain phosphorous? If its true then how alfred hershey and martha chase used the statement that proteins do not contain phosphorous?
Yes some of the proteins contain phosphorus but in the experiment (Hershey and chase experiment) they used bacteriophage it's protein sheath contains carbon,hydrogen,nitrogen and sulphur while the DNA in the bacteriophage contains carbon,hydrogen,nitrogen and phosphorus(in the acid) so they selected this for that experiment moreover sulphur is absent in the DNA but phosphorus is not so one can conclude that DNA is the thing that was transferred
