Translation, the second half of the protein synthesis process, is reviewed in this nifty handout. Young DNA experts explain what codons are and how they work. They label diagrams and differentiate between introns and exons. The worksheet is of high enough quality to photocopy and distribute. One of the diagrams is in color; however, so you might want to have learners access the worksheet online for best viewing and simply write their answers on a separate sheet of paper.
