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?
No two individuals, other than identical twins, have the same DNA.
Are there any downsides to DNA evidence?
There are a few downsides to DNA evidence: It has been suggested that the prominence of DNA evidence on TV shows has caused juries to expect irrefutable DNA evidence before convicting someone. This may be a problem if other forms of evidence are ignored. DNA evidence can only be obtained in instances where biological substances are left behind or exchanged. This only occurs in a minority of cases. DNA evidence sometimes only proves that the person was present at the scene - it does not always prove guilt. However, if a person's DNA is found at the scene, this may be perceived as proof that they committed the crime.

Who invented DNA fingerprints?
Fingerprint evidence and DNA evidence have NOTHING to do with one another except the fact that they are both collected by a crime scene technician. Fingerprints are the recoverable oily residue left by the pads of your fingers. DNA evidence is concerned with bodily fluids and the unique chemical/biological makeup of them that is unique to all individuals. The only similarity between these two concepts is that both fingerprints and DNA are totally unique to each individual and are, therefore 100% accurate in identifying people.

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.
