Answer :

Answer:

Not all DNA that was found at the scene has to be related to the scene.

Explanation:

Just because DNA was found at the scene, that doesnt mean that they were actually there of guilty. For example, a hair of Person A cound be carried over to another scene on Persons B's clothing.

DNA evidence analysis is an imperfect science because DNA is a very unstable and degradable molecule in the environment, furthermore, an DNA evidence analysis may present DNA molecules that are unrelated to the purpose of the analysis.

A DNA evidence analysis aims to:

  • Find biological traces in one location.
  • Determine those responsible for activities carried out in that location.
  • Determine the genetic makeup of a living being.

This type of analysis is usually done in a place where there was a crime and it is necessary to do a DNA analysis to identify the culprits and victims.

The problem with this analysis is that DNA is a molecule that degrades quickly when outside the body. In addition, a location may have a very large variety of DNAs, which may belong to living beings unrelated to the crime, or to the purpose of the analysis.
