Q. Statement I : In an experiment conducted by Avery et al, the transforming substance was not a protein or RNA
Statement II : In experiment conducted by Avery et al, the proteases and RNases do not affect transformation.

Molecular Basis of Inheritance

Solution:

• Protein-digesting enzymes (proteases) and RNA-digesting enzymes (RNases) did not affect transformation, so the transforming substance was not a protein or RNA.
• Digestion with DNase did inhibit transformation, suggesting that the DNA caused the transformation.
