SAY IT WITH DNA: PROTEIN SYNTHESIS WORKSHEET: Practice Pays
Having studied the process by which DNA directs the synthesis of proteins, you should be ready to decode some DNA
"secret" messages. To do this, you must follow the procedure of protein synthesis as this is taking place right now in your cells; no
short cuts! Practice these steps by following and finishing the partially solved message below.
STEP 1: "Build" the mRNA molecule, matching the RNA nucleotides to the DNA nucleotides properly, letter by letter.
(For purposes of simplicity, it will be assumed that this mRNA is bacterial; there are no introns to cut out!)
STEP 2: Figure out the tRNA triplets (codons) which would fit the mRNA triplets (letter by letter).
STEP 3: Look up each tRNA codon in the tRNA Dictionary (below), and find the corresponding symbol and amino acid
abbreviation for that codon. Record that one-letter symbol (and its amino acid) below each codon. "Spc" = "space". If you have
done this correctly, the…
