What else can I help you with?
Do you think DNA fingerprinting is good evidence for solving crimes. why or why not?
Yes, DNA fingerprinting is a powerful tool for solving crimes because it can definitively link a suspect to a crime scene or victim. DNA evidence is scientifically reliable and has high accuracy, which can help prosecutors secure convictions or help exonerate innocent suspects. However, it is important to consider the chain of custody and proper handling of DNA samples to ensure the integrity of the evidence.
Why was it difficult to use DNA as evidence in a crime pcr was invented?
you need many copies of DNA for DNA fingerprinting
What year was fingerprinting first used as evidence?
Fingerprinting was first used as evidence in 1892 when Sir Francis Galton, a British scientist, published a study on the uniqueness and permanence of fingerprints. This marked the beginning of the modern usage of fingerprints for identification and evidence in criminal investigations.
What is the purpose of DNA fingerprinting?
Purposes of DNA fingerprinting include; · Medical research · Diagnose inherited disorders · Develop cures for inherited disorders · Match recipients of live organs from donors, making transplants more successful · Forensic evidence · Immigration evidence and paternity evidence · Solve crimes (Forensic science) · Identify an individual, individuals family, and to identify a body · Breeding animals, conserving nature and understanding evolutionary process By R.R 2012
How are DNA fragments separated on DNA fingerprinting?

How conclusive is DNA fingerprinting evidence?
DNA evidence is very conclusive and some say 99% accurate, however it is possible to challenge it based upon faulty collection and/or faulty lab techniques. All evidence can be contaminated by faulty collection and preservation methods and it leaves the evidence open to challenge. One key component to preserving any evidence is maintaining a secure chain of custody of any collected evidence. from the time of collection to the end of the case in court every movement of the evidence must be documented.
Why was it difficult to use DNA as evidence in a crime pcr was invented?
you need many copies of DNA for DNA fingerprinting
Why was it difficult to use DNA as evidence in a crime before PCR was invented?
you need many copies of DNA for DNA fingerprinting
What evidence can be used for DNA fingerprinting at a crime scene?
DNA evidence from blood, hair, saliva, or other bodily fluids found at the crime scene can be used for DNA fingerprinting. This evidence is compared to the DNA profiles of suspects to determine if a match exists, helping to identify or exclude individuals involved in the crime.

How reliable is DNA fingerprinting?
It is not infallable, but it is considered reliable enough to be use as evidence.

Two parents think their baby was switched at the hospital. It is 1968 so DNA fingerprinting technology does not exist yet. The mother has blood Type O the father has blood Type AB and the baby and?
The blood types do not provide conclusive evidence of parentage. In this case, further investigations such as proper hospital records, family medical history, and physical characteristics can be used to verify parentage in the absence of DNA fingerprinting technology.
What affects has DNA fingerprinting had in the UK?
Routine DNA fingerprinting of any person arrested for ANY offence has meant many previously un-solved crimes have been cleared, due to evidence preserved at the scene being matched against the police DNA database.
