Explanation: DNA can be a great source of information when used as a forensic evidence. This technique has many advantages and disadvantages when used as a source of information in case of crime.

Identical twins: There are some common fragments of DNA that is same in identical twins so it can be a difficulty in deciding the criminal.

Not enough of a sample: DNA should be present in a detectable amount to be used an sample for evidence, less than this detectable amount is a waste and cannot be used as a sample for evidence.

Contaminated and degraded sample: If the sample of DNA is contaminated or degraded then the result might be incorrect and might not be used as a sample for forensic evidence.

Hence, the correct answers are all of the above.

Which membrane gives eukaryotes an advantage over prokaryotes in protecting their genetic material from damaging chemical change

Anarel [89]

That would be the nuclear membrane. Eukaryotic cells have a nucleus that encases their DNA, so it stays safer than it would in a prokaryotic cell.
