Role of early genetic engineering for animal

Explanation:

Genetic engineering is the process of artificial alteration or manipulation of the original genetic makeup of an organism and then modification and recombination using technologies like the DNA recombinant technology.  

Early genetic engineering began with expressing specific bacterial genes by Cohen in 1973. Later due to various anxieties arising about hazardous reshaping of genetic systems, it came to a slowdown.

Then all these anxieties were subdued with the advent of DNA recombinant plasmid-based technology which was very helpful to understand the molecular genetic mechanisms in animals.

In animals genetic engineering is mainly used to find genes responsible for beneficial traits or characters introduce them into another animal’s genome and create a new offspring with the beneficial character.

The first animal which was created by genetic engineering was a mouse by Rudolf Jaenisch in 1974. Later many transgenic animals were developed like chicken, mice, cattle, sheep, pig etc.
