Describe how forensic scientists determine the likelihood
that the DNA profile of a random person in the population
would match that of a sample found at a crime scene.
Step by step
Solved in 2 steps
- Why is DNA evidence more useful as exclusionary evidence than for positive identification of a suspect?What does a guy need to do (e.g. how different does his DNA profile need to be?) to be excluded as a possible contributor to a DNA profile from an evidence sample?Should DNA phenotyping be used to identify or convict a suspect?
- How do you think DNA fingerprinting has aided the Criminal Justice System in its ability to determine the guilt or innocence of an individual?investigative units can use DNA fingerprinting to analyze a crime scene. Explain how this is doneand why all of us have unique DNA fingerprints.Though initially a promising technique, DNA profiling has had limited use in determining innocence and guilt of individuals in criminal cases. Group of answer choices True or False
- Refer 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. Take notes on whether any of the suspects’ DNA shares the same bands as the crime-scene DNA. Analyze your notes on each suspect’s DNA profile. Do any suspects share all the DNA bands found in the evidence DNA?What innovative techniques or methodologies in forensic analysis have been developed in the field of biology to enhance the identification and analysis of biological evidence at crime scenes?Suppose you are arrested for a serious crime and a DNA profile is created and entered into databases. Later, you are proven innocent. Should you have the right to have your DNA profile removed from all databases?
- 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. Q7: Present a brief argument of what can be learned from the DNA evidence presented in the gel above. Hints: a) Which, if any, of the suspects is connected to the crime scene? b) What else is interesting about the DNA fingerprints of two of the other suspects?Based on the bands in the image below, which suspect was at the crime scene? Crime DNA Supeets Suspect 1 Suspect 2 Suspect 3 Suspect 1Suppose one of two identical commits a crime and only DNA, Fingerprints, and an Eyewitness account are evidence in the case. Which of the following evidence can actually be useful?
