Symptoms of conjugate gaze palsies include the impairment of gaze in various directions and different types of movement, depending on the type of gaze palsy. Signs of a person with a gaze palsy may be frequent movement of the head instead of the eyes.
Agarose is used to separate DNA because it has a neutral charge and low chemical complexity - meaning it is unlikely to react with biomolecules. It is also an easily cast and handled matrix. Plus, samples are very easy to recover when you use agarose gel. 4 people found this useful.
Typically, a DNA molecule is digested with restriction enzymes, and the agarose gel electrophoresis is used as a diagnostic tool to visualize the fragments. An electric current is used to move the DNA molecules across an agarose gel, which is a polysaccharide matrix that functions as a sort of sieve.
