Investigator Sheer is testifying about DNA evidence she found at the crime scene that matches the suspect on trial. The prosecutor asks Investigator Sheer to explain her conclusion that the DNA samples matched. What would be a good explanation for her to give to the jury?

That at least 10 different points on the two samples matched
That the DNA profile matches someone with the suspect's hair color and skin tone
That she found one point that matched on the two DNA samples
That the DNA samples showed no clear points in common

She will give the DNA fingerprinting report to the jury which will have samples of suspect and its profile matching to the evidence found at the scene of crime.

In DNA fingerprinting hair, blood, semen, or other biological samples are required for the comparison of suspect and evidence. It depends on the unique polymorphism in their DNA.
The fragments of DNA are made to run on the electrophoresis gel and the similar bands observed will confirm the matching.
The DNA fingerprinting will provide very exact evidence if the DNA samples matched.
