Explanation:
Detailed explanation-1: -Gel electrophoresis is used to separate macromolecules like DNA, RNA and proteins. DNA fragments are separated according to their size. Proteins can be separated according to their size and their charge (different proteins have different charges).
Detailed explanation-2: -What does analyzing DNA using gel electrophoresis allows researchers to identify and study? It allows researchers to study specific genes, to compare them with the genes of other organisms, and to discover the functions of different genes and gene combinations.
