I am sure, a lot of boys and girls want blue eyes. Isn`t?
Can genetic engineering and DNA sequencing technology make it happen? I believe that it`s gonna come in near future.
I was doing some research on the gene of BLUE eyes and I found out that the gene name called HERC2 is responsible to have blue color eyes in Human beings. It has been found out that people with blue eyes usually have a mutation in HERC2 that leads to change in the function of another gene called OCA2 which ultimately leads to change in the color of eyes.
But guys, HERC2 is a big gene of 15000-17000 bp. Now I am sure most of you will ask what is 15000 bp. Bp is base pair and our human DNA is made up of 3 billion base pairs. Now you will ask what is a base pair? There are 4 base pair i.e., A,G,C and T and our human DNA of 3 billion base pair is made up of only 4 letters [A,G,T,C] in different combinations. Each living being on this earth- humans, dogs, plants. insects, cats everyone has these base pairs but all of them have different number of base pairs.
So, out of these 3 billion letters, 15000 base pairs makes a gene called HERC2 which is responsible for many small functions in human body. But the interesting one is the change in color of eyes. And geographically, this gene and humans with blue eyes are most prominent in North and East Europe and some parts of North Africa and Americas.
I am not saying that this is going to easy but the cosmetic industry already have there eyes on this gene and they are going to come up with new strategy to get you the blue eyes using DNA sequencing and DNA editing technology.
Just remember a part of HERC2 is the gene of BLUE EYES. It`s coming……
