Detailed explanation-1: -Gel electrophoresis of DNA fragments plays a central role in the diagnosis of hereditary disease. Electrophoretic separation of differently sized fragments enables the characterization or typing of normal variants which are known to be genetically linked to disease genes.
Detailed explanation-2: -Gel electrophoresis is a technique used to separate DNA fragments (or other macromolecules, such as RNA and proteins) based on their size and charge. Electrophoresis involves running a current through a gel containing the molecules of interest.
Detailed explanation-3: -Recombinant DNA technology comprises altering genetic material outside an organism to obtain enhanced and desired characteristics in living organisms or as their products. This technology involves the insertion of DNA fragments from a variety of sources, having a desirable gene sequence via appropriate vector [12].
Detailed explanation-4: -If the DNA sample from a suspect matches the DNA at a crime scene, then that signifies that the suspect in question was present at the crime scene (although the suspect may not have committed the crime).
