DNA – Deoxyribo Nucleic Acid
Deoxyribonucleic acid is the hereditary material in all known living organisms containing the genetic instructions used in their development and functioning. The DNA segments carrying this genetic information are called genes. It is is found inside a special area of the cell called the nucleus.
The code of DNA is made up of four chemical bases name :-
- Adenine (A)
- Guanine (G)
- Cytosine (C)
- Thymine (T)
DNA bases pair up with each other, ie. A with T and C with G, to form units called base pairs.
The strands of the DNA make a copy of each and becomes two stands. This is the reason why humans gives birth to humans, eagle to eagle, horse to horse and so on for every type of living creature.
