According to the genetic code,some amino acids are encoded by more than one codon. This characteristic of the genetic code is . . . . . . .

The chemical method developed by which of the following scientists was instrumental in synthesizing $\text{RNA}$ molecules with defined combinations of nitrogen bases?

The sequence of a processed $m-RNA$ is given as $5'-AUG\ CUA\ UAC\ CUC\ CUU\ UAU\ CUG\ UGA-3'$. How many amino acids will be present in the polypeptide chain translated from this $m-RNA$?

Whose experiments cracked the $DNA$ and discovered unequivocally that a genetic code is a "triplet"?

The sequence of amino acids in a polypeptide is determined by which of the following?

$A$ polypeptide is produced as dictated by $mRNA$. The number of bases on the $mRNA$ that code for the polypeptide portion containing the $N$-terminal amino acid and the next $13$ amino acids is:
