Answer:
It depends entirely on an equation, certain equations are meant to confuse you with numerous answers so taht you have to narrow it down, some only have one or a few. It really depends on the type of problem
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:
- Extraction and purification of the DNA from the fingerprint.
- PCR amplification to obtain high yield.
- Fragmentation of the DNA by use of restriction enzymes.
- Gel electrophoresis analysis of the fragmented DNA.
- Analysis of gel to compare the size of the bands.
