We, Homo sapiens (and every other organism on the planet), become what we are on the basis of the genes we inherit from our parents at the time of our birth. Whether you are tall, short, dark, dusky or fair, have great hair, good health - everything depends on these genes. Earlier these genes were believed to be 'tamper proof' and they could not be manipulated. But the human brain and contemporary science does not deem anything as impossible. Thus, we came up with a concept called genetic engineering. Genetic engineering refers to the process of directly tackling an organism's genes. Molecular cloning and transformation is used in genetic engineering for changing the structure and nature of genes. This technology has brought about a sea change in farming and in human genetics.
GE in Human itself
The first and one of the most prominent genetic engineering pros is that genetic disorders can be prevented by identifying those genes which cause these diseases in people. The use of genetic engineering to prevent diseases is called gene therapy. This can be extremely advantageous especially when women screen their unborn babies for genetic defects. If there is a chance that the baby can have genetic defects, it can prepare the mother and the doctors before and after the baby delivered. In advanced cases, those problem genes can be corrected.
In addition to that, infectious diseases can be controlled and effectively dealt with by implanting genes which code for the antiviral proteins particular to each antigen. Humans can be developed or formed to reflect desirable characteristics. It is being said, theoretically though that this process can drastically change human genomes. This would facilitate in helping people regrow their limbs and other organs. In addition to this, people can be made stronger, faster and smarter, by using genetic engineering in the future. In other cases, if a gene exists in nature which can be
