Question

In your own words, describe what information the visible DNA fingerprint provides for each DNA sample

Answer 1

Answer:

The visible DNA fingerprint can help extract DNA which, after analysis, can accurately identify the suspect or perpetrator of the crime.

Explanation:

DNA Fingerprinting:

• DNA fingerprinting is a molecular analysis tool that can help identify a suspect in a crime through DNA extracted from fingerprints.
• Specific patterns in the DNA, known as polymorphisms, can be identified through DNA fingerprinting.
• The DNA fingerprinting process involves:

1. Extraction and purification of the DNA from the fingerprint.
2. PCR amplification to obtain high yield.
3. Fragmentation of the DNA by use of restriction enzymes.
4. Gel electrophoresis analysis of the fragmented DNA.
5. Analysis of gel to compare the size of the bands.
