Which is the primary purpose of using restriction enzymes in gel elctrophoresis?

• It allows the strands of DNA to be cut into various lengths for testing
• It restricts the number of base pairs that can be tested in a sample
• It makes the testing simpler by moving the strands into the gel faster
• It charges the DNA strands
