If a cell is fed radioactive phosphate in the culture medium, macromolecules like membrane lipids, DNA, RNA will become highly radioactive.
What are the biological macromolecules?
- Biological macromolecules are the naturally occurring components in the cell which are necessary for the growth and survival of the living organisms.
- The four important types of biological macromolecules are lipids, carbohydrates, proteins and nucleic acids (DNA and RNA).
- Phospholipids are phosphorus containing lipids containing two fatty acid chains, a glycerol unit and a phosphate group which are present in the membrane and play a structural and metabolic role in the cell.
- Nucleic acids contain phosphorus as phosphate group which provides energy. ATP (Adenosine triphosphate) contains 3 phosphate groups out of which one gets released for energy forming ADP and subsequently AMP and vice versa.
