Which of the following describes the experimental strategy that was used to decipher the genetic code?
a. comparing the amino acid sequences of proteins with the base sequence of their genes
b. analyzing the sequence of RNAs produced from known DNA sequences
c. analyzing mutants that changed the code
d. examining the polypeptides produced when RNAs with particular sequences were translated

Identify the main goal of the experimental strategy, which is to decipher the genetic code.
Consider the process of translation, where RNA sequences are used to synthesize polypeptides.
Evaluate each option to determine which one directly involves observing the relationship between RNA sequences and the resulting polypeptides.
Option a involves comparing amino acid sequences with gene sequences, which is more about understanding gene expression rather than deciphering the code.
Option d involves examining polypeptides produced from specific RNA sequences, which directly relates to understanding how RNA sequences determine amino acid sequences in proteins.
