Complete the statement
In double-stranded DNA: A = {0} and G = {1}, so (A+G) = (T+C).
Instructions
Fill in Chargaff's base-pairing equalities.

The START codon in eukaryotic mRNA translation is:

  1. UAA (one of three stop codons)
  2. UAG (one of three stop codons)
  3. AUG (codes for methionine, start)
  4. UGA (one of three stop codons)
Show answer and solution

Correct answer: C. AUG (codes for methionine, start)

AUG is the START codon and also codes for methionine. Translation always begins at the first AUG in proper context. Stop codons (UAA, UAG, UGA) terminate translation.
