The Oboe. The oboe is a soprano-range, double-reed woodwind instrument of length 62 cm. Its wooden tube is distinguished by a conical bore expanding at the end into a flaring bell. The modern oboe's range extends from the B-flat below middle C (B3-flat) to the A nearly three octaves higher (A6).
RFLP analysis requires a biological sample about the size of a quarter, but PCR can be used to reproduce millions of copies of the DNA contained in a few skin cells. Since PCR analysis requires only a minute quantity of DNA, it can enable the laboratory to analyze highly degraded evidence for DNA.FLP analysis requires a biological sample about the size of a quarter, but PCR can be used to reproduce millions of copies of the DNA contained in a few skin cells.

What happens to DNA evidence? Once DNA is collected, there is a protocol for how the evidence is handled and used in an investigation. The evidence will be provided to law enforcement who may send it to a crime lab. The lab will analyze the material and develop DNA profiles that are unique to a specific person. The lab works with law enforcement officials to compare these profiles to the DNA of potential suspects. If the perpetrator is unknown, they may compare the DNA profile against a large database run by the FBI called CODIS, the Combined DNA Index System.
