Question

illustrates Fraenkel-Conrat and Singer’s experiment on the genetic material of TMV. What results would you expect in this experiment if protein carried the genetic information of TMV instead of RNA?

Methods
Type A TMV
Type 8 TMV
Degrade both
types of TMV
to yield
RNA and
coat proteins.
RNA
Mix RNA of
one type with
protein
of the other.
Type A Type B Type B Type A
RNA
protein
RNA
protein
to create
hybrid viruses
Hybrid TMV
Hybrid TMV
Infect tobacco
with the hybrids.
Tobacco
RNA B
RNA A
Results
Protein A
Protein B
The type of RNA
in the hybrid
parent TMV
determines the
RNA and protein
of the progeny
viruses
Conclusion: RNA is the genetic material of TMV.
