OKLAHOMA CITY - DNA is something heard in courtrooms and even television shows.

Now, a DNA Analyst with the Oklahoma State Bureau of Investigation breaks down how DNA is used and strikes down the misconceptions.

Dr. Rhonda Williams from the OSBI recently sat down with Kevin Ogle for the DNA dialogue.

Williams says DNA is a powerful tool because it is unique for the person you are looking for.

She says the more locations you have of DNA, the more information you have about the person, suspect, or case.

According to Williams, DNA hasn't changed.

It's the process of how DNA is analyzed and used.

Williams says DNA techniques have gotten more sensitive, and can now pick up the slightest traces of DNA, such as skin cells.

Even if there is no suspect, there's a DNA database of offenders and other evidence gathered that the DNA can be measured against.

There are also some misconceptions about DNA.

Williams says people may think the DNA will tell investigators what kind of disease they have, or is capable of cloning an individual.

She says that's not the case, and that DNA is only used to tell gender and if that person is matched to another crime or criminal database.
