Explanation:

Step1: Transcribe DNA to mRNA

DNA: CCG → mRNA: $\text{GGC}$ (A↔U, T↔A, C↔G, G↔C)

Step2: Find tRNA anticodon

mRNA: GGC → tRNA: $\text{CCG}$ (complementary to mRNA)

Step3: Match mRNA to amino acid

Use codon chart: mRNA GGC corresponds to glycine (Gly)

Answer:

mRNA codon: GGC
tRNA anticodon: CCG
amino acid: Gly
