DNA Diagnostics, Inc. is committed to helping our customers understand the science of DNA typing, the methods and tests used to identify human DNA, their usefulness and limitations, and the various legal questions raised by attorneys and judges prior to and during trial. DNA Diagnostics, Inc. has provided training to prosecutors, defense attorneys, investigators, and law enforcement officials on effective DNA evidence handling, chain of custody procedures, specialized trial tactics, and effective presentation of DNA evidence in the court room. Workshops have also been designed to provide a basic understanding of the ABCs of DNA, as well as a thorough background of the molecular techniques used to determine an individual’s identity (i.e., a DNA profile) or parental lineage.

DNA typing courses are available that are designed to provide the participant with an understanding of the principles and methodologies used in RFLP and PCR-based analyses. The practical applications of RFLP analysis, coupled with the use of PCR-amplified products of specific human DNA regions, are emphasized in selected topics for those in the legal professions as well as for forensic and research scientists. Customized workshops, seminars and Continuing Legal Education (CLE) programs are also available upon request to suit our customer’s needs. An outline of an often requested workshop, which focuses on effective presentation of DNA evidence in a jury trial, is presented below.
