Question

Gel electrophoresis is often used in forensics. Look at the gel on the right. From the evidence DNA, which individual matches the DNA evidence left at the crime scene?

Answer 1

Suspect #2 matches the evidence.

Step-by-step 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.
