Answer:

Suspect #2 matches the evidence.

Explanation:

Gel Electrophoresis can be described as a molecular biology technique which is used to separate DNA, RNA and proteins based on their molecular sizes. Usually the different samples of the DNA are compared to a standard sample to see which of the suspected samples matches with the standard one.

In the diagram above, the bands from the gel electrophoresis show that the suspect 2 has the most similarities with the standard DNA sequence taken from the crime scene. Hence, he might be the culprit.
