How can techniques of molecular biology be used to analyze dna for the presence of the fh mutation?

The techniques of molecular biology may be used to analyze DNA for the presence of the FH mutation through gel electrophoresis, compare patient DNA to DNA positive for FH mutation. Gel electrophoresis is a technique used to separate mixtures of DNA, RNA, or proteins according to molecular size. Molecules to be separated are pushed by an electrical field through a gel that contains small pores. 

Bis the correct answer.

Iwould say overuse ( but not 100% sure ) in the u.s. we tend to overuse water by leaving it running, throwing it away, taking long showers, etc.
