Question

which dna sequence, trna anticodon, and amino acid correspond to the mrna codon uaa? 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 uaa
trna anticodon
amino acid

Explanation:

Step1: Find complementary DNA sequence

mRNA is synthesized from template DNA via complementary base pairing: A pairs with T, U pairs with A, C pairs with G, G pairs with C. For mRNA codon UAA, the DNA sequence is $\text{ATT}$.

Step2: Find tRNA anticodon

tRNA anticodon is complementary to mRNA codon: A pairs with U, U pairs with A. For mRNA UAA, the anticodon is $\text{AUU}$.

Step3: Identify amino acid

Check the codon chart: UAA is a stop codon, so the amino acid is STOP.

Answer:

DNA sequence: ATT
tRNA anticodon: AUU
amino acid: STOP
