B. PCR

C. FISH

D. Southern blot

 

Show Answer

Correct Answer » A

Explanation

The term RFLP (Restriction Fragment Length Polymorphisms) refers to single base-pair substitutions in the germline DNA of different individuals that either destroys or creates a new recognition site for a given restriction enzyme. 
PCR is used to amplify a specific region of a DNA strand (the DNA target).
FISH is a technique used to identify the presence of specific chromosomes or chromosomal regions through hybridization (attachment) of fluorescently-labeled DNA probes to denatured chromosomal DNA.
Southern blotting combines the transfer of electrophoresis-separated DNA fragments to a filter membrane and subsequent fragment detection by probe hybridization
