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 .
