De la agricultura a la ingeniería genética.

Genetic engineering, as part of biotechnology, is simply the last step of the evolution of the traditional methods used in agriculture. The first farmers learned to select and combine plants to create new varieties of maize, soy, tomato, etc.; this process is known as a crossover or hybridization. Nevertheless, to obtain the aimed results one requires enough time and effort. For example, to confer a certain characteristic from one plant to another one sexually compatible, the farmer crosses them and transfers, together with the intended gene, thousands of others. In general, genetic engineering is a tool that allows scientists to identify and select those genes that produce beneficial characteristics. A single specific characteristic can be chosen and be transferred to a plant, this process is highly selective, precise and fast.
