The Genetic Code

  • Write out the complementary strand of DNA below the strand shown and be sure to label the 5’ and 3’ ends of the complementary strand.

  • There are six possible reading frames in double-stranded DNA. Using the genetic code, translate all possible reading frames of this DNA sequence, keeping in mind the following rules.
    • In RNA, the T becomes a U, so everywhere you see a T in the sequence, read it as a U.
    • The genetic code is read in the 5’ to 3’ direction.
    • Use the single-letter abbreviations for the amino acids because that is what is commonly used by computer programs.
  • - will be used in place of a stop codon
