There are four nitrogen bases in DNA, A, T, C, and G. Erwin Chargaff discovered that 'A' pairs with 'T' and 'C' pairs with 'G.' Remember, "When I hike the appalachian trail, I take a cute guy/girl."

James Watson and Francis Crick won the Nobel Prize for discovering that DNA has a double helix shape, which is like a twisted ladder (escalera retorcida).

I remember this because I like to go hiking in the woods on the AT (Appalachian Trail). I take my husband with me and he's a CG (cute guy).

Use each amino acid chart below to determine which amino acids are coded for by the mRNA codons above. If you do it correctly, the answers you get on both charts will match. Be sure you know how to use both, as you don't know which one you will be given on the summative assessment or SOL test.
