Question
Chapter 15, Problem 14TYU
Summary Introduction
To determine: The suspect’s DNA that matches the evidence as shown in the given figure.
Introduction: Short tandem repeats (STRs) are 3-7 base pairs repetitive sequence elements that are scattered throughout the human genome. These polymorphic loci can be amplified and compared with the standard sample to know about the origin of biological samples.

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.
Questions:
Answer questions 1 to 3 about this gel electrophoresis.
1. Which color represents the smallest DNA fragment?
(explain)
2. If “A" is the crime scene and B to E are suspects. Do
you have any match? (Why or Why not)
3. Is there a possibility that any of the suspect related
to the person who committed the crime? Explain.

- Should DNA phenotyping be used to identify or convict a suspect?arrow_forwardRefer to the DNA profiles comparing the DNA obtained from the three suspects with the crime-scene DNA. 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.
