DNA

It has been always a debate between faith and science. People believed that it was environment and external forces that determined the nature of a person. However, with the discovery of DNA the debate has tilted over science

Throughout history, people have speculated on the substance that carries the instructions to make life. What carries hereditary information from one generation to the next? How does it all work?

Your DNA is like your thumbprint. It is unique and your DNA structure is yours alone. Unless you have an identical twin, no one else on the planet has exactly the same DNA as you have.

In the nucleus of almost every cell in your body is the collection of DNA needed to make you. DNA in the nucleus is grouped into 23 sets of chromosomes that are known as "genome." In each chromosome, the DNA is grouped into "genes." Your genome contains about 30,000 genes. Each gene carries information that tells the cell to make a unique protein that will perform a special function.

How does something so small contain all of the instructions to make your whole body and keep it working?

That is answered in the chemical makeup of DNA. If you think of your genome (all of your chromosomes) as the book that makes you, then the genes are the words that make up the story. They do that by making proteins, which do most of the real work in the body.

Firstly let us briefly look into the history of DNA
