DNA Technologies

Since the discovery of DNA, advances in genetics have enabled scientists to understand the human genome and the genetic makeup of other organisms. Utilizing genetic information, scientists have the ability to modify DNA and replicate DNA efficiently. Many laboratory techniques have developed as a result of genetics research, including polymerase chain reaction (PCR), cloning, gene splicing, gene therapy, and DNA fingerprinting. While much of the work done in the field of genetics has yielded positive outcomes, there are ethical issues with this new technology.
