Document Summary
Biotechnology existed some 10,000 years ago - people used microorganism in the processes of making bread, cheese, alcoholic drinks and leather. French chemist louis pasteur showed that living yeast or other microorganisms were necessary for the fermentation that produced wine, beer and other products. Improvements in microscopes allowed scientists to begin exploring the cell"s inner structures toward the end of the century. Molecular biologists had known since 1941 that genes contain instructions for making proteins, the complex chemicals that do most of the work of the cell. In the early 1970s scientists dev the ability to change genes instead of deciphering them. Gerg"s technique for gene splicing allowed researchers to in effect slice and dice genes, sandwich them in any order and pack them to go . Boyer, cohen and other scientists were soon using viruses as vectors or transmission agents for inserting foreign genes into bacteria and later plant and animals cells.
