Multiple choice

A triplet base sequence in DNA reads ATT. What will be the corresponding mRNA anticodon, and amino acid called by this DNA?

  1. TAA; UTT; methionine

  2. TAA; AUU; no amino acid (= stop codon)

  3. UAA; AUU; no amino acid (= stop codon)

  4. CGG; GCC; alanine

C Correct answer
Explanation

The complementary base-pairing rules of DNA-to-RNA and RNA-to -RNA give the codon and anticodon. Recall also that there is no thymine in RNA; uracil and adenine are complementary bases for RNA.
