In this article we will discuss about the molecular structure of nucleic acid with the help of diagrams. Nucleic acids constitute another important group of biological macromolecules present in all types of organisms where they function mainly as store-house of genetic information and as information- transfer molecules. Two types of nucleic acids: i. Ribonucleic acid (RNA) and ii. Deoxyribonucleic acid [...]
In this article we will discuss about the molecular structure of proteins with the help of diagrams. Quantitatively, proteins are the chief organic components of most living organisms, as also of viruses. About 50% of the dry weight of bacterial cells is protein. The flagella, pili and fimbriae are made up entirely of proteins, and the cell membrane, cytoplasm, ribosomes [...]
The below mentioned article provides notes on the Krebs’ Cycle. The TCA cycle or Krebs' cycle (after H. A. Krebs) is a cyclic sequence of reactions through which pyruvic acid produced in the EMP and EDP is oxidized. The cycle operates in aerobic organisms including animals, plants and microorganisms. The main function of the cycle is to generate energy by [...]
