Describe a controversy over the use of dna microarray

Explanation:

The use of DNA evidence in regard to a crime begins with the collection of the evidence from the scene. This may come in the form of hair, a drink bottle or food item, among many other things. When the sample is brought to the lab, the DNA is first extracted from the cells present on the evidence. The amount of DNA that the item contained is determined through the quantification process, and because the amount is likely very small, the DNA is amplified. Amplification is a procedure in which multiple copies of a DNA sample are produced for further testing and characterization.
