Forensic DNA Fingerprinting

Separation of DNA will assist with the determination of which of the following?

• Paternity

• None of these

• Forensics

• Bioremediation

How many areas of short tandem repeats does the FBI use in DNA Profiling?

• one

• ten

• Thirteen

• twenty

What is the main difference between genes and short tandem repeats (STRs)?

• Genes are unique to each individual, while STRs are the same for everyone

• Genes determine physical traits, while STRs determine genetic diseases

• Genes are found in the middle of DNA, while STRs are found at the ends

• Genes have multiple copies, while STRs have only one copy

What is the potential risk of having a DNA database?

• Contamination of DNA samples

• Increased privacy concerns

• Higher insurance premiums

• Limited access to genetic information

DNA fingerprinting is primarily used for which of the following purposes?

• Identifying genetic disorders

• Determining paternity

• Criminal identification and forensic investigations

• Cloning organisms

Which DNA testing method involves cutting DNA into fragments using restriction enzymes and separating them by size using gel electrophoresis?

• PCR (Polymerase Chain Reaction)

• RFLP (Restriction Fragment Length Polymorphism)

• STR (Short Tandem Repeat)

• DNA fingerprinting

What is the primary advantage of using PCR in DNA analysis?

• It requires a large amount of DNA sample.

• It can amplify small amounts of DNA to produce enough material for analysis.

• It provides the most detailed DNA profile.

• It is the fastest method available.

Which DNA testing method is most commonly used in forensic science due to its high discrimination power and ability to analyze degraded samples?

• RFLP

• PCR

• STR

• DNA fingerprinting

When selecting a DNA testing method, which factor is NOT typically considered by forensic scientists?

• The type of sample available

• The size of the sample

• The cost of the testing method

• The information needed from the analysis

What is the primary purpose of forensic DNA fingerprinting?

• Identifying genetic disorders

• Determining paternity

• Criminal identification and forensic investigations

• Cloning organisms
