Question

Accepted Answer

# Explanation:
## Step1: Transcribe DNA to mRNA
Base pairing rules: DNA T→mRNA A, DNA A→mRNA U, DNA C→mRNA G, DNA G→mRNA C; reverse direction for mRNA (3' to 5' matches DNA 5' to 3').
## Step2: Map mRNA to amino acids
Use standard codon table; stop codons (UAA, UAG, UGA) end translation; write first 3 letters of amino acid.
