A DNA Whodunit?
Problem: Gasp! Someone has stolen some candy from Mrs. Koester’s supply closet! To figure out who
stole the candy, you must decode the DNA ransom note left by the criminal. To do this, you will first
need to transcribe the mRNA from the DNA for each line of the message. Then, using the mRNA
alphabet decoding chart, translate the mRNA into the message. If you can answer the question in the
message, you can identify the criminal!
DNA Line One – GGA GAC AAA CGG ATA CCG TAC CAG TTT AGA AAG TAG AGC CCA ACT
DNA Line Two – GGT TAG TAC TTC AGT ATG TTT TCC TAC ACC ATG TCC GGG TCT AAC AAG AGA GTC
