  Polymerase Chain Reaction (PCR): Unveiling the Blueprint of Precision DNA Amplification In the world of molecular biology, few techniques have had as profound an impact as the Polymerase Chain Reaction (PCR). This revolutionary process, developed in the mid-1980s by Kary B. Mullis, has transformed the field of genetics, medicine, forensic science, and countless other disciplines. By allowing scientists to amplify specific DNA sequences with incredible precision, PCR has unlocked new frontiers in research, diagnostics, and technology development. Understanding PCR: The Molecular Copy Machine At its core, PCR is a molecular copy machine that enables the rapid amplification of a specific segment of DNA. It achieves this through a repetitive cycling process that generates millions to billions of copies of the target DNA sequence. The beauty of PCR lies in its simplicity and versatility, making it a cornerstone technique in modern molecular biology laboratories. The Components of PCR ...

  DNA (A Bio-molecule) DNA stands for deoxyribonucleic acid. DNA is one of the most essential bio-molecules found in living organisms. DNA is a life-defining molecule. This molecule transfers information from parent to offspring. It is involved in transferring the genetic information from one cell to next cell (mitosis).     DNA Replication is a natural phenomenon which ensures that each dividing cell is receiving the same and equal amount of information as found in the parental cell. DNA is a most fundamental molecule which has the information stored to a particular characteristic to a living organism. Most of the living organisms have DNA as a hereditary material. DNA is more stable than RNA because it has a deoxyribose sugar. Apart from that, the basic components of DNA are nucleotides made from nitrogenous base, pentose sugar, and phosphate molecule.    DNA has three basic elements in its chemical structure i.e. 5-carbon ribose sugar, Phosphate, an...
