- You are a forensic scientist in charge of DNA samples in a case where a man was murdered. You conduct gel electrophoresis on the samples to determine the DNA profile of the samples. The rows of bands have been marked to make it easier to reference the bands. The sample marked 'evidence' came from under the victim's fingernails, likely indicating a struggle. There are two suspects in the case, both of whom are brothers, they are marked suspect 1 and suspect 2, for brother 1 and brother 2, respectfully. Does the evidence collected match the DNA profiles of either brother? If yes, which one? If no, then would it be likely that the actual criminal is a family member of the brothers? If yes, what could the relation be (mom, dad, cousin, aunt, or uncle)? Note: there is a sister in their family, their parents are both still alive, and they have a robust extended family. The brothers are not twins.arrow_forwardWhen working with the gel electrophoresis chamber, what must we keep in mind? A. Keeping the gel flat on the table without any buffer solution B.

Use a ruler to align the bands found under the crime-scene DNA with any of the bands found in the suspects’ DNA. Place the ruler at the bottom of the bands.

Do any suspects share all the DNA bands found in the evidence DNA?arrow_forward
