>It is defined as the manufacturing of new products with the help of biological agents such as micro organisms.
>The process of use of biology in making new products for the benefits of the society is called as Biotechnology.
>The process of gene manipulation or genetic engineering to obtain the desired products is known as Biotechnology.
The term Biotechnology was point out by Karl Ereky in 1917.
>It refers to the use of micro organism in their natural state i.e. without gene alteration.
For example : Curd, bread etc.
>When there is a alteration in genetic material of microbes for getting desired products, it is known as modern biotechnology.
>This technique is also called as genetic engineering or R-DNA Technology.
