KNOW YOUR DNA



DNA stands for Deoxyribo Nucleic Acid. DNA is a hereditary material in humans and almost all other organisms that is passed from one generation to the other . DNA contains the instructions an organism needs to develop. These instructions are found inside every cell and are passed down from our parents to their children. The entire human genome contains about 3 billion base pairs 600 crores and about 25000 genes.

DNA is made up molecules . The information in DNA is stored asa a code made up four chemical bases Adenine (A), Cytosine (C), Guanine (G) and Thymine (T).  These DNA  bases.  These DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide.  




    Necleotides are arranged in two long stands that from a spiral called a double hellix. The structure of the double helix of somewhat like a ladder with the base pairs forming the ladder's rungs and the sugar nd phosphet moleclues forming the vertical side pieces of the ladder. The order of the nitrogen bases on DNA sequence from gene, which in the language of the cell, which tell the cells how to make protein. Another type of Nucleic Acid ribonucleic acid (RNA) translates genetic information from DNA proteins.
