Question

What are the pros and cons of DNA fingerprinting?

Answer 1

DNA Fingerprinting:

1. DNA fingerprinting is a molecular biology technique that is used to determine the genetic composition of an individual.
2. DNA fingerprinting is based on the unique differences that are present in our DNA sequences.
3. DNA fingerprinting is used for lineage studies, crime investigation, as well as paternal disputes during unclaimed pregnancies.
4. DNA fingerprinting is based on VNTRs or a variable number of tandem repeats.
5. VNTRs are repetitive sequences of DNA that are present in all organisms. Minor variations that are unique to a particular organism form unique identifications for every organism's DNA.
6. VNTRs form the basis of DNA Fingerprinting.

Pros of DNA Fingerprinting:

1. DNA fingerprinting is a non-invasive and painless medical technique to gather genetic data.
2. DNA fingerprinting is useful for a wide variety of cases ranging from crime investigation to evolutionary studies.
3. DNA fingerprinting also helps solve parental disputes to determine the paternal partner in cases of denial.
4. DNA fingerprinting is easily accessible from body fluids, or hair follicles.

Cons of DNA Fingerprinting:

1. DNA fingerprinting can be misused due to its easy accessibility.
2. Performing the test without someone's prior knowledge is a violation of privacy.
3. This information could be handled by third parties to wrongly convict an innocent individual.
