What is DNA ?
DNA, or deoxyribonucleic acid, is that molecule of heredity that stores the information needed for building and supporting all living structures. Consider it as an organic guide, written in a mysterious language, which explains to cells how to develop, work and multiply. DNA exists in almost all your cells; it is always contained in the nucleus and often wound intricately into thread-like strands called chromosomes.
At its core, DNA is made of four chemical bases: A, T, C, and G. These bases form the rungs of the ”twisted ladder” structure in that they always attach with each other with A pairing with T, and C pairing with G. The sequence of these base pairs works as a blueprint or as set of directions — they form your eye colour to how your body synthesises proteins which are the building blocks involved in several processes within the body.

That is why your DNA is 50% from your mother and 50% from your father and that of no other person in this world is a carbon copy of yours. That is why family members contain many of the same characteristics within them. It is also the basis by which some diseases or traits can run in a certain families or in the family tree.
That of the fact that although DNA is so tiny, the data contained within contains an almost unbelievably large amount of information. If all the DNA in a single human cell was to be placed end to end the entire length would be two meters long!/
People use DNA to analyze life, diagnose inherited conditions, and solve cases, with the assistance of scientists. Which procedures like the DNA sequencing assist in unlashing the genome, a complete set of genetic instructions. From creating individualized medicine maps to finding family roots, DNA’s role is felt in almost every possible branch of today’s world.
