A commercial site. We aim to educate those who may not have as much experience with biology and biotechnology while at the same time providing quick access to biology-related resources for those who are dealing with much more specific and detailed information. Has lots of federal information especially related to agricultural biotechnology. This directory contains 1000 URLs specific to biotechnology, pharmaceutical development, genetic engineering, medical device development, and related fields such as pharmacology and toxicology. It differs from Biosciences in that Biotechnology places more emphasis on product development and the delivery of products and services.
