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.

A DNA nonmatch is considered conclusive, however, because any variation in DNA structure means that the DNA samples have been drawn from different sources. An example from the early 1990s illustrates the way in which DNA evidence is used in the criminal justice system. After a Vermont woman was kidnapped and raped in a semi-trailer truck, police identified Randolph Jakobetz, a truck driver, as a suspect in the crime.
