Question

short notes on genetic engineering ​

Answer 1

Genetic engineering is considered as a kind of biotechnology. This is a process in which the alteration of the genetic make-up of cells is done by deliberate and artificial means.

This process involves transfer or replacement of genes to create recombinant DNA. This can be done by cutting DNA molecules at specific sites to get fragments containing desirable and useful genes from one type of cell.

Thereafter, these genes can be inserted into a suitable carrier or vector. Now, these recombinant DNA can be put into completely different cell of a bacterium or plant or animal cell. By this technique they acquire useful characteristics, such as disease resistance or to make useful enzymes, hormones, vaccines, etc.
