The Applications of Biotechnology are discussed here which is applied in various fields now a days such as agriculture, medicine, Food industry, Pharmaceutical industries etc, Let us define what is biotechnology. With the help of genetic engineering (Biotechnology) using various living organism or their parts or components , different types of products which are used at commercial level are made. Such as Crops which are pest resistant, hybrid animals with high nutritional value are made with the help of biotechnology.. Some of the applications of biotechnology are as follows. Biotechnology can be used to grow better crops, hybrid crops can be made which gives high yield and disease resistant. Value added product of plants or crops can be made with the help of biotechnology. Crops yield can be improved by introducing specific genes into the plants using biotechnology, this genes are resistant to insects, resistant to environmental stress such as (heat, cold, drought) and tol...
