In an mRNA molecule, a group of three nitrogenous bases makes up a codon, and each codon codes for an amino acid. There are four different nitrogenous bases that can be arranged into different codons, but there are only 20 different amino acids. Based on this information, what conclusion can you make about the genetic code?

Each codon can be translated into more than one possible amino acid

Many of the possible combinations of nitrogenous bases do not code for anything and are not involved in gene expression.

Several different codons result in the production of the same amino acid.

anonymous · Answer

During translation, nitrogenous bases are rearranged into a sequence that corresponds to an amino acid.
