The markers revealing variations at DNA level are referred to as molecular markers. Which among the following molecular markers make the use of non- PCR-based approach?

ARFLP

BRAPD

CAFLP

DSSRs

Answer:

A. RFLP

Read Explanation:

  • RFLP (restriction fragment length polymorphism) method is a technique in which the DNA of various individuals is fragmented by restriction endonucleases and is separated by gel electrophoresis.

  • Restriction Fragment Length Polymorphism or RFLP is a non-PCR based approach.

  • The RFLP analysis differentiates or compares individuals based on polymorphisms in their genome.

  • These polymorphisms are detected by restriction digestion and the subsequent comparison of the lengths of the restriction fragments.
