PCR

 As we stride into an era of unparalleled scientific innovation, the future of Polymerase Chain Reaction (PCR) stands at the forefront of breakthroughs in molecular biology and diagnostics. PCR, a cornerstone technique revolutionizing genetic analysis, continues to evolve, promising even greater precision, speed, and versatility. 🌐 Expanding Horizons: PCR's applications transcend traditional boundaries, from disease diagnosis and forensics to environmental monitoring and beyond. With ongoing advancements, its reach extends to novel fields such as synthetic biology, personalized medicine, and point-of-care testing, democratizing access to crucial information and accelerating research endeavors globally. 💡 Innovative Technologies: Emerging technologies like digital PCR, droplet PCR, and isothermal amplification techniques are reshaping the landscape, offering enhanced sensitivity, multiplexing capabilities, and streamlined workflows. These innovations not only refine existing appli

Enzymes: what they are and what they do

Figure of enzymes meeting a substrate and forming a new product (peptide bond) Enzymes: what they are and what they do Right now, as you read this, there are billions of chemical reactions happening inside your body. Although they happen at lightning speed inside cells, when these reactions are run inside test-tubes --- in a lab instead of a body --- they happen at a snail’s pace. What explains this difference in speed? What do our cells have, that a test-tube lacks? The answer is: enzymes! Enzymes are life’s great facilitators. They create the conditions needed for biochemical reactions to happen fast. The general name that chemists use for a chemical entity that increases the speed of a reaction is a “catalyst.” Enzymes are biological catalysts--they catalyze the chemical reactions that happen inside living things. The definition of catalysis Consider a chemical reaction where a molecule A bonds with a molecule B to create a molecule A-B (A stuck to B). Under a given set of condition
