Here's a fun way to test your students ability to translate DNA bases into amino acids...
I wrote out about 9 different strings of DNA bases (I just typed A, C, G, T at random).
For example:
ACTGTATGCTTGATGATGCGTAATGCTAGTTCCTGATGCTAGC
Each student was given one of the strands of DNA. She then needed to determine the amino acids coded for by that DNA.
The student then went to a station where there were beads - one color for each amino acid.
The appropriate beads were strung onto a length of lanyard lacing attached to an index card.
After the amino acid sequence was complete, the student brought me the completed protein, which I quickly compared to my completed strands (pictured above). It was quick and easy to check their work.
I had students return the beads to the appropriate bags after they finished. You could let yours turn their protein into a key chain, if you were so inclined.
