Paragraph: 
Biotechnology is technology based on biological applications. These applications are increasingly used in medicine, agriculture and food science. Biotechnology combines many features of biology, including genetics, molecular biology, biochemistry, embryology, and cell biology. Many aspects of biotechnology center around DNA and its applications, otherwise known as DNA technology. We could devote a whole textbook to current applications of biotechnology, however, we will focus on the applications towards medicine and agriculture, and the extension into the forensic sciences. First, though, we need to understand DNA technology.
