Hardbiology
Which of the following is NOT required for any of the techniques of DNA fingerprinting available at present?
Select the correct option:
Solution
Incorrect! Answer:
Zinc finger analysis
- DNA Fingerprinting Techniques: Modern techniques like VNTR analysis involve multiple steps.
- Required Components:
- Restriction enzymes for cutting DNA.
- PCR for amplifying small samples.
- Southern Blotting and DNA-DNA hybridisation for detection.
- Non-required: Zinc finger analysis is a research tool for studying how proteins bind to DNA but is not part of the standard DNA profiling workflow.
- Conclusion: Zinc finger analysis is the correct answer.
