In RAPD (Random Amplified Polymorphic DNA), random primers are used to amplify DNA regions, so \textit{species-specific primers are not required} in RAPD. This is one of the reasons why RAPD is a quicker and simpler method than RFLP (Restriction Fragment Length Polymorphism).
(1) Why Other Options Are Correct:
- RAPD is a quick method compared to RFLP: RAPD is faster because it uses random primers and does not require restriction enzyme digestion of DNA.
- RFLP is more reliable than RAPD: RFLP is considered more reliable because it involves well-defined markers and precise patterns of DNA fragments.
- Radioactive probes are not required in RAPD: RAPD typically uses non-radioactive methods for detection, making it safer and easier to use than RFLP, which often involves radioactive probes.
Conclusion:
The statement species specific primers are required for RAPD is incorrect because RAPD uses random primers.
