Explanation

Biotechnology deals with techniques of using live organisms or enzymes from organisms to produce products and processes useful to human.
`**` In this sense, making curd, bread or wine, which are all microbe-mediated processes, could also be thought as a form of biotechnology
`**` However, it is used in a restricted sense today, to refer to such of those processes which use genetically modified organisms to achieve the same on a larger scale
`**` Further, many other processes/techniques are also included under biotechnology. For example, in vitro fertillisation leading to a 'test-tube' baby, synthesising a gene and using it, developing a DNA vaccine or correcting a defective gene, are all part of biotechnology
