Answer: B) Histidine- glycine - glycine - tyrosine - glycine.
Explanation: Amino acids are coded for by three nucleotide sequence found in an mRNA molecule. These three nucleotide sequences are known as codons. Every amino acid is coded for by at least one codon. Some amino acids are coded for by more than one codon. The phenomenon by which more than one codon codes for a particular amino acid is known as degeneracy. The codons are said to be degenerate.
From the information provided, CAU codes for histidine, GGU, GGC and GGG code for glycine while UAC codes for tyrosine.
