Answer;
D. 5' UUA GGA GAU AGA 3'
The mRNA sequence that codes for the amino acid sequence leu–gly–asp–arg
5' UUA GGA GAU AGA 3'.
Explanation;
A codon is a sequence of three DNA or RNA sequence that corresponds with a specific amino acid or stop signal during protein synthesis.
In this case; UUA codes for amino acid Leucine, GGA codes for glycine, GAU codes for aspartate and AGA codes for arginine
