What is Buffer and What are the Importance in Biological system?

What are the Buffers? What are the Importance?

Buffers are the mixture of weak acids and their salts of strong bases (or) the mixture of weak bases and their salts of strong acids. Buffers help to maintain a normal pH of the biological systems. When an acid (or) alkali has added the pH of the solution changes in the absence of buffers. What … Read moreWhat is Buffer and What are the Importance in Biological system?

What is DNA Polymerase and its function in DNA Replication

DNA Polymerases in prokaryotes and eukaryotes

The first postulate the central dogma, experimentally proved and is that the DNA is capable of self-replication. This was immediately deduced by Watson and Crick that each DNA strand uniquely specifies its complement, but it took longer for the details of the mechanism are elucidated. The first question was that of conservation of replication mechanism. The now … Read moreWhat is DNA Polymerase and its function in DNA Replication

What is Fidelity of DNA Replication in Normal?

fidelity of DNA Replication in normal

DNA replication is, by far, the most accurate of known enzyme-catalyzed processes. The error rate per base pair per round of replication is about 10-9 to 10-10. The accuracy cannot be explained, however, by the different binding energies between correct and incorrect base pairs (this amounts to only a 100 to 1000 fold difference between … Read moreWhat is Fidelity of DNA Replication in Normal?

What are the Basics of pH concept and its Importance?

ph concept basics

The nature of the solution (acidic, alkaline (or) neutral) can be represented in terms of either hydrogen ion concentration (or) hydroxyl ion concentration. This naturally explains the pH concept. In 1909, Sorenson used a logarithmic scale for expressing the H+ concentration. This scale was called “pH”, Where “P” stands for ‘Power’ and ‘H’ for hydrogen … Read moreWhat are the Basics of pH concept and its Importance?

What are the importance of Coupling Reactions in Biological Systems?

coupling reactions

What is a coupling reaction? Before going to discuss this, we need to know about Energy. Energy is the capacity to do work and appears in many different inter-convertible forms: light, heat, electrical, mechanical and so on. Energy can be kinetic (‘active’) or potential (‘stored’). Water behind a dam represents a store of potential energy … Read moreWhat are the importance of Coupling Reactions in Biological Systems?
