Question

which dna sequence, mrna codon, and amino acid correspond to the trna anticodon ugc? use complementary base pairing and this codon chart to answer the question. write the amino acid using its three - letter abbreviation. write stop for a stop codon. dna sequence
mrna codon
trna anticodon ugc
amino acid

Explanation:

Step1: Find complementary mRNA codon

tRNA anticodon: UGC. Complementary base pairing (A-U, T-A, C-G, G-C) gives mRNA codon: $\text{ACG}$

Step2: Find complementary DNA sequence

mRNA codon: ACG. DNA is complementary (T pairs with A, G pairs with C, C pairs with G) and uses T instead of U: $\text{TGC}$

Step3: Match mRNA to amino acid

Use codon chart: mRNA codon ACG corresponds to threonine (Thr)

Answer:

DNA sequence: TGC
mRNA codon: ACG
amino acid: Thr
