The Work of Beadle and Tatum Not Apply to Every

Question

The work of Beadle and Tatum not apply to every gene.Why not?
A) Genes never encode polypeptide sequences
B) Some genes encode RNA sequences that do not lead to the formation of polypeptides
C) Some genes encode other DNA sequences that do not lead to the formation of polypeptides
D) All of these are correct
E) None of these

Accepted Answer

Beadle and Tatum's work described the relationship between genes and the polypeptides they encode, but not all genes code for polypeptides. Some genes code for RNA molecules that do not lead to the formation of polypeptides. Therefore, Beadle and Tatum's work does not apply to these genes.
