What is DNA ?


Our earth is filled with wide variety of living organisms. We can find atleast one living thing from deepest sea to tallest mountains . Scientists have discovered nearly 13 lakhs of different species which includes bacteria to blue whale . The future of every living being is  decided at one place i.e, DNA . DNA means Deoxyribonucleic acid .DNA was first discovered by Friedrich Miescher in 1869.

                                               DNA contains nearly 20,000 to 40,000 Genes . Now we should know the difference between The DNA and Genes . For example :- If DNA  is a library , Genes are books present inside it .


                                                Every living being contains DNA having data related to their own body . The shape of the DNA is Double – Helix . DNA is made up of adenine , thymine , guanine and cytosine molecules . These molecules are there in sequence .  The length of DNA extracted from each cell is 2 meters of length . A living organism – How to Born, How to grow, How to behave etc., are decided by DNA . So, if we are a computer then DNA is our software . 

How DNA get Damaged ?


1.     UV rays coming from sun .
2.     Due to some chemicals or narcotics DNA get damaged .


3.     During smoking time .
4.     Due to some occurrence in the sequence of molecules , DNA get damaged.

Facts about DNA:-


1.     Our DNA is 98 % similar to chimps DNA .
2.     Nearly 10 lakh times,  DNA get damaged every day.
3.     According to a study , we can store 215 petabytes of data can store one gram of DNA.
4.     Our DNA  could stretch 600 times from Earth to Sun and back.
5.     According to a study , we may receive effect from our ancestors of 14 generations .
