How many prime elements we can get if we analysis a living cell?
Almost 20 types of atoms are used in living cell.
The elements Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N), Phosphorus (P), and Sulfur (S) are found in all living things. If Calcium (Ca) is included, these seven elements make up approximately 99% of the human body (weight).
Sometimes some gene gets over expressed in organism, so which molecular technique can help us to detect the over expression of that gene?
