im aware of the transforming principle experiment done by Frederick Griffith, Avery , McLeod and McCarty and the Hershey and Chase experiment. All these experiments point to DNA as the molecule that carries genetic information , but there is still the possibility of contaminations of proteins and /or RNA since DNA came originally from a biological source (cells) Can a experiment be designed that it will 100% prove the case? or what can be done to ensure that the possibility is close to a 100% .
Re: Can we be 100% sure that DNA is the transforming principle
