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.

STR DNA, which is used for human identification, is extracted from nucleated cells. The ability to obtain reliable DNA profiles from fingerprints depends on the number of nucleated cells collected from the fingerprints. The more cells there are in a stain or on a surface, the more DNA there will be. If there are very few cells available, it is referred to as low copy number DNA profiling..
