How DNA use in real life?
DNA has many uses in real life. These uses may include use as evidence in a crime scene for example
How reliable is DNA fingerprinting?
It is not infallable, but it is considered reliable enough to be use as evidence.
How do they use DNA evidence today?
DNA evidence is used in criminal investigations to link suspects to crime scenes, identify victims, and exonerate innocent individuals. It is also used in paternity testing, identifying bodies in mass disasters, and studying genetic inheritance and evolution. DNA evidence is a powerful tool due to its accuracy and unique nature.

National Commission on the Future of DNA Evidence
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.
What are three things forensic scientists use DNA fingerprinting for?
iDENTIFING RELATIONSHIPS, CORSPES, 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.
How do forensic scientists use DNA?
Forensic scientists use DNA analysis to identify individuals, solve crimes, and establish paternity. They compare DNA samples from crime scenes or suspects with samples from victims or relatives to make matches and draw conclusions about the evidence. DNA can provide crucial evidence in criminal investigations by linking individuals to crimes through biological material such as blood, saliva, or hair.
Why do investigators use DNA instead of other physical evidence?
Because DNA is unique to each person so it can be used to kinda say they were definatly involvd cos it couldn't be anyone else's DNA
