Answer

  1. A codon in mRNA is read in a non-contiguous fashion.

Explanation:

  1. Codon in mRNA consists of three nucleotides and is read in a contiguous manner.
  2. Genetic code is same in every organism with some exceptions. Hence, it is nearly universal.
  3. Genetic code is degenerate as more than one codon may code for an amino acid.
  4. Genetic code is unambiguous as a particular codon will always code for the same amino acid.
