This method is good for separating large DNA fragments in a low-percentage, low-melt agarose gel by an angled electrical field that periodically changes orientation.
A) RFLP
B) Southern blot
C) Agarose gel electrophoresis
D) PFGE

Question

Quizplus · Accepted Answer

The method described in the question is pulsed-field gel electrophoresis (PFGE). PFGE is specifically designed for separating large DNA fragments and uses an angled electrical field that periodically changes orientation to improve resolution. RFLP and Southern blot are techniques used to analyze DNA fragments after electrophoresis, and agarose gel electrophoresis is a general technique for separating DNA fragments but does not involve PFGE.
