Biological basis
This concept in biology refers to the production of crops and plants for animal and also human consumption where the recent molecular biology is used. The main objective is to enhance certain desired characteristics or traits. There is also an increase in the nutritional content. The entire process of modification is taken under artificial laboratory conditions in order to increase herbicides resistance. A good example is the Bacillus thuringiensis that produce crystal proteins which engulf insect larvae. The application is in the corn plant. The following are the biological ground that start and favor the genetically modified crops and plants.
First, the technique increases the crop and plant resistance to pests and diseases. This is because losses that result from insect pests can destroy crops and plants which can result to big financial losses the case of farmers. In addition, they cause starvation in countries that are developing.
Second, these crops can act as herbicide. This helps to prevent environmental pollution since farmers stop using more herbicides. For example, there is a strain created by Monsanto of soybeans which is genetically modified so that it cannot be adversely affected by product Roundup as herbicide.
Third, genetically modified crops and plants are able to tolerate conditions of coldness which can destroy the seedlings. For example, there is an introduction of an antifreeze gene that come from cold water fish in has tobacco and also potato. These genes ensure that plants are able to endure in the cold temperatures that normally kill unmodified seedlings.
Forth, there is tolerance of modified crops and plants in conditions of drought and salinity. In the modern world, where land as a resource has become scarce, farmers are forced to grow crops in such areas that were previously unsuited in terms of cultivation. So the technology of creating plants and crops which endure high salt or acidic content in soil and also...
