I. CASE ANALYSIS. Read carefully the scenario below and answer the questions that follow.
A bank was robbed in broad daylight. The CCTV cameras were not working and the police ruled it out to be
an inside job. While looking for pieces of evidence in the vault room, you found a strand of hair. As a forensic
scientist, you know that this piece of evidence can be a key to solving a crime. The hair was placed in a sample
bag and was sent to the lab for DNA amplification using polymerase chain reaction. You also gathered hair
samples from the employees that are in the bank. The lab sent the DNA sequence of the hair found in the vault
room.
Located in Row A below is the DNA sequence of the hair found in the vault room. In Row 1, give the
complementary base pair of the DNA sequence and transcribe the DNA strand into mRNA in Row 2, then,
translate that strand into a polypeptide chain, identifying the codons in Row 3, the anti-codons in Row 4, and the
amino acid sequence in Row 5. Úse the Translation table provided as vour reference. Don't forget to give the
directionality of all the sequences.

Compare the amino acid sequence you obtained from the crime scene and the amino acid sequence of
the employees. Who among the bank employees could be the bank robber? Why did you say so?
