According to the text describing the salient features of the genetic code: (i) The code is degenerate because some amino acids are coded by more than one codon. (ii) The codon is read in mRNA in a contiguous fashion without punctuations (implying it is non-overlapping). (iii) The code is unambiguous (non-ambiguous) and specific, meaning one codon codes for only one amino acid. Options suggesting the code is 'overlapping' or 'ambiguous' are incorrect.
