What is gel electrophoresis?
A technique used in DNA fingerprinting and other processes in which molecules migrate through a gel (such as a polyacrylamide gel) and separate into bands according to size

HINT: THIS IS ONE OF SEVERAL USES OF THE ANSWER
DNA Modification
Elements that have properties of both metals and nonmetals; sometimes referred to as semiconductors
Metalloids
Elements that are typically not shiny, are usually gases or brittle solids, are not malleable, and are poor conductors of heat and electricity
Nonmetals
