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 is DNA evidence difficult to refute in court?
DNA evidence is difficult to refute in court because it is highly accurate and reliable. The technology used to analyze DNA is advanced and has a low margin of error, making it a strong piece of evidence. Additionally, DNA profiles are unique to each individual, making it highly improbable for someone else to have the exact same DNA profile.
Are there any downsides to DNA evidence?
While DNA evidence is powerful in identifying suspects and solving crimes, there are potential downsides. These may include human error in sample collection or processing, the possibility of contamination leading to false results, privacy concerns related to storing genetic information, and the potential for misuse in cases of bias or misinterpretation.
Who invented DNA fingerprints?
DNA fingerprints were invented by British geneticist Sir Alec Jeffreys in 1984. He discovered that specific regions of a person's DNA could be used to create a unique genetic profile, which could be used for identification purposes.
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 is it difficult to use DNA as evidence in a crime before PCR was invented?
Before PCR was invented, it was difficult to use DNA as evidence in a crime because traditional methods required a large amount of DNA sample, which may not have been available or may have been contaminated. This made it challenging to obtain reliable DNA profiles for comparison. Additionally, the older techniques were more time-consuming and less sensitive than PCR, making the process of analyzing DNA evidence slower and less accurate.

Which country invented cotton?
No country "invented" it. It's a plant which has been in existence before DNA restructuring was a thing. IIRC, the oldest evidence of cotton was found at Mehgarh, which is located within present day Pakistan.
Why is it difficult to extract DNA from mummies?
Because the fragments that can have DNA extracted are quite small and can't even give evidence, describe or identify one single gene.
What are the arguments for and against DNA evidence?
There are many arguments for and against DNA evidence. One argument is that it cannot be disproved as deciding evidence.
Are there any downsides to DNA evidence?
While DNA evidence is powerful in identifying suspects and solving crimes, there are potential downsides. These may include human error in sample collection or processing, the possibility of contamination leading to false results, privacy concerns related to storing genetic information, and the potential for misuse in cases of bias or misinterpretation.
Can DNA evidence be washed away?
There are a few types of DNA. Some of them such as blood can be washed away. This is why its important that if someone is attacked they should go to the hospital before taking a shower. Some such as the DNA in your hair cannot be washed away.
