Basics
What is another name for DNA fingerprinting?
Restriction Fragment Length Polymorphism (RFLP).
What is the first step in DNA fingerprinting?
DNA extraction and isolation.
Name one real-world application of DNA fingerprinting.
Forensics
What is one ethical concern surrounding DNA fingerprinting?
The potential misuse of genetic information.
What is one forensic use of DNA fingerprinting?
Identification in criminal cases
What percentage of human DNA is identical across all humans?
Over 99%.
What type of enzymes are used to cut DNA at specific sequences?
Restriction enzymes or restriction endonucleases.
What is DNA fingerprinting used for in paternity testing?
To compare DNA band patterns between a child and potential parents.
What personal right could DNA fingerprinting infringe upon?
The right to privacy
How can DNA fingerprinting improve healthcare?
By identifying genetic markers for hereditary diseases and enabling early detection
What are the variations in DNA sequences that DNA fingerprinting uses called?
Polymorphisms.
What is a restriction site?
A specific sequence of bases where restriction enzymes cut DNA.
How is a suspect’s DNA matched to a crime scene?
By comparing the DNA band patterns in the crime scene to the suspect’s.
How can errors in the DNA fingerprinting process affect criminal cases?
They can lead to wrongful convictions or exclusions.
How does DNA fingerprinting help in conservation efforts?
It helps monitor biodiversity, identify endangered species, and aid in reintroduction and breeding programs.
Which type of DNA regions are typically analyzed in DNA fingerprinting?
Non Coding Regions
Why do DNA fragments differ in size after being cut by restriction enzymes?
The location and number of restriction sites vary due to polymorphisms.
What does it mean if a suspect’s DNA bands do not match those at a crime scene?
The suspect is not the source of the DNA evidence.
Name two possible causes of errors in DNA fingerprinting analysis.
Contamination and mislabeling of samples.
What role does DNA fingerprinting play in personalized medicine?
It helps tailor medications to an individual's genetic makeup.
What is one exception where DNA polymorphisms do not create unique fingerprints?
Identical Twins
How are specific sequences in DNA fragments detected during the visualization step?
Using probes that bind to complementary sequences.
What online was mentioned that allows users to simulate DNA fingerprinting?
A DNA fingerprint simulation with step-by-step instructions.
How might bias affect the accuracy of DNA fingerprinting?
Bias in the analysis or interpretation could lead to incorrect results or discrimination.
What is one evolutionary application of DNA fingerprinting?
It helps track evolutionary changes and relationships among species.
