Which of the following is not the characteristic feature of genetic code?
The codon is triplet
The code is nearly universal
The code has punctuations
Some amino acids are coded by more than one codon, hence the code is degenerate
According to the salient features of the genetic code, the codon is read in mRNA in a contiguous fashion and there are no punctuations (it is comma-less). The other options describe correct features: the codon is a triplet, the code is nearly universal (e.g., from bacteria to humans), and the code is degenerate (some amino acids are coded by more than one codon).
