It will serve as a starting point for the introduction of a routinely used genetic engineering tool for DNA amplification. Thus, in my forensics science course, I hope to review basic DNA biology and genetics. With the prevalence of DNA in the media, my students naturally have a fascination for its applications in the real world. 2 Furthermore, many of the victims of 9/11 were identified using DNA identification technology. 1 Today, the Innocence Project states that nationwide 309 post-conviction DNA exonerations have occurred showing yet another use of DNA beyond its gene therapy potential. The application of DNA testing in crime cases began in 1984 with Alec Jeffreys' work on DNA fingerprinting. This is especially true in the field of DNA forensics. The last 50 years have seen an explosion of scientific and technological advancement in DNA technology. New frontiers in biotechnology, genomics, and biomedical engineering are driving a debatable question, "How much information is too much information." But, what is DNA? Does the average person or student really understand the science of the DNA tests they hear about? If you had the ability to predict the diseases or conditions you may have, would you want to know? How important is it to know everything? These are some questions that can be explored through study of genetics and genetic engineering. The field of genetics has gone beyond simply mapping the sequence of human DNA. It seems that you can't turn on the television without a CSI (Crime Scene Investigation) or Maury Povich show asking for the results of a DNA test. Genetic identification, paternity testing, genetically modified foods, and gene therapy are some of the applications in which genetic engineering is widely used today.
