What technique is used to alter the dna

Genetic Engineering is a technology through which DNA can be altered.  We can alter it either by editing or removing a part of DNA, with the help of this technology.

One of the GE technique is CRISPR-CAS 9 which stands for (clustered regularly interspaced short palindromic repeats and CRISPR-associated protein 9).

Though it is a long race to win but scientists are developing ways to cure genetic disorders in human beings via CRISPR-CAS9.
