Individual Journal Assignment
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.
- Note: For the full list of codons, see this RNA Codon Table. The stop codon is indicated by "x".
