Two blood samples A and B picked up from the crime scene were handed over to the forensic department for genetic fingerprinting. Describe how the technique of genetic fingerprinting is carried out. How will it be confirmed whether the sample belonged to the same individual or two different individuals?

Explanation

### Step-by-Step Solution for Genetic Fingerprinting

1. **Isolation and Extraction of DNA**: The first step in genetic fingerprinting is to isolate and extract DNA from the blood samples. This is typically done using a process called centrifugation, which separates the cellular components from the liquid portion of the blood, allowing for the extraction of DNA.

**Hint**: Remember that centrifugation helps separate different components based on density.

2. **Restriction Digestion**: After extracting the DNA, the next step is restriction digestion. In this process, restriction endonucleases (enzymes) are used to cut the DNA at specific sequences. This results in the formation of DNA fragments of varying lengths.
