PROTEIN SYNTHESIS WORKSHEET

Use your codon chart to determine the amino acid sequence. Remember to read through the strand and ONLY start on AUG and STOP when you reach a stop codon (UGA, UAA, or UAG). Follow the example in the box. Abbreviate the proteins using the first three letters of the amino acid name or use the chart provided on page 2.

( Example: DNA AGA CGG TAC CTC CGG TGG GTG CTT GTC TGT ATC CTT CTC AGT ATC mRNA UCU GCC AUG GAG GCC ACC CAC GAA CAG ACA UAG GAA GAG UCA UAG protein start - glu - ala – thr – hist– asp – glu - thr - stop )
