GUU, GUC, GUA
GAU, GAC, GAA
GGU, GGA, GGC
GGU, GGA, GCU
Correct option is C. GGU, GGA, GGC
The standard genetic code is represented as an RNA codon because, when proteins are made in a cell by ribosomes, it is mRNA that directs protein synthesis.
Glycine is an amino acid, a building block for protein. The genetic code of glycine is GGU, GGA, GGC.
So, the correct answer is 'GGU, GGA, GGC'
