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?
Step by step
Solved in 3 steps
- Should DNA phenotyping be used to identify or convict a suspect?what does DNA tests tell us about the time frame or circumstances under which DNA came to be associated with an evidence sample? It depends on the sample Who was the primary wearer of an article of clothing If the DNA was depositied as a part of the crime or from innocent contact The order in which the individuals contributed DNA to an evidence sampleState the five basic steps of DNA fingerprinting using the RFLP method. Why do you think the PCR method is of more use in crime scene investigations?
- Which of the following criteria do you feel is the most important one to optimize for a DNA profiling methods? Speed Discriminating power Sensitivity Cost False Positive Ratewhat is an working overall photograph in forensicsDiscuss the principle of DNA fingerprinting. How would you use the technique to find out a criminal in forensic studies ? Explain.
- Do you think it should be possible to convict criminals solely on gel electrophoresis of digested DNA samples? Why or why not?You are a police investigator assigned to solve a case of house robbery. In your investigation, you discovered a small quantity of blood and a sample of skin in a piece of broken glass from the window where the thief entered. No usable fingerprints were even obtained. What can you do with this samples to help you identify the prime suspect?The two main functions of biometrics are ___________and _________ .
- DNA profiling identifies a person by the similar parts of his or her DNA True FalsWhat is DNA fingerprinting? Mention its application.Since DNA anaylsis is specific to human body fluids such as blood, why do Crime Scene Investigators even bother with doing field test for biological fluids? Why not submit all samples that might have any kind biological fluid to the lab?
