One codon codes for only one amino acid,hence the code is

$A$ 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:

In $mRNA$,$AUG$ is the initiation codon and $UAA$,$UAG$,and $UGA$ are termination codons; therefore,a polypeptide cannot be synthesized beyond any of these triplets to the end of the $mRNA$. Which one of the following $mRNA$ sequences can be translated completely?

The terms $Gene$ and $Cistron$ are sometimes used as synonyms because:

There are $64$ types of codons in the genetic code dictionary because:
