[Biotechnology. Genetic engineering. Chemico-pharmaceutical area]

We have tried to bring up to date the information on in vitro Genetic Manipulations and the Recombinant DNA considering its relations with new technology and possible applications towards the fine chemicals development and specially drug area. Taking into account the scientific development which takes place in the most advanced industrial societies, those countries which are nowadays developing an adequate technology level must face the scientific challenge among them, we can find two which appear as specially important: the Genetic Engineering knowledge and the Molecular Biology developments.
