Question

Restriction fragment length polymorphisms (RFLPs)

• A. can be subjected to gel electrophoresis
• B. are the basis for DNA fingerprints
• C. identify individuals genetically
• D. all of these

Answer 1

The correct option is D all of these

Restriction Fragment Length Polymorphism is a technique that exploits variation in homologous DNA sequences. It refers to a difference between samples of homologous DNA molecules from differing locations of restriction enzyme sites and to a related laboratory technique by which these segments can be illustrated. In RFLP analysis, the DNA sample is broken down into pieces (digested) by restriction enzymes and the resulting fragments are separated according to their length by gel electrophoresis.

So, the correct option is 'all of these'.
