- 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_forwardIs DNA information considered to be Big Data?arrow_forwardwhat does DNA tests tell us about the time frame or circumstances under which DNA came to be associated with an evidence sample?

- Q7 is based on the DNA fingerprint below presented to jurors in a murder trial. Lane 1 represents DNA taken from the murdered victim. Lane 2 through 5 are DNA samples taken from suspects in the crime. Lane 6 is from a bloodstain found near the victim.
