DNA Probe!! Probes are usually labelled radioactively or chemically to make them easier to detect, thus revealing the target DNA sequence.
 * DNA probe:** A specific sequence of single-stranded DNA used to bind to a complementary DNA (or RNA) sequence of.

By marking the probe, it is possible to visualize whether the DNA is present in the genetic material. This forms the basis for DNA diagnostics. ||
 * || Short piece of DNA that is complementary to a specific piece of DNA in the cell.

The prorbe has a sequence that matched something in your DNA and it will help the investigator to determine whose DNA it was. If they found two peoples DNA, and if they needed to determine whose DNA it was, the probe will attach to the persons DNA that matches with the sequence in the probe. A probe is going to look for a tiny piece of your DNA. Probes are tiny compared to the DNA in your cells. - the Probe will provide you with a pattern of your DNA. The suspect has the darker double lines. and the victim has the thiner lines (on the far right).
