1. Introduction The Polymerase Chain Reaction (PCR) is a groundbreaking molecular biology technique that enables the selective amplification of a specific DNA sequence from a tiny amount of starting genetic material. This technique was developed by Kary Mullis in 1983, for which he was awarded the Nobel Prize in Chemistry in 1993. PCR has revolutionized … Read more
Applications of Recombinant DNA Technology and Genetic Engineering in the Production of Interferon, Vaccines (Hepatitis B), and Hormones (Insulin) Introduction Recombinant DNA (rDNA) technology and genetic engineering have transformed modern medicine by enabling the large-scale production of therapeutic biomolecules that were once rare, costly, or difficult to extract from natural sources. By manipulating genetic material … Read more
Introduction The field of genetic engineering and molecular biology has revolutionized the biological sciences, enabling scientists to manipulate genetic material for research, industrial, agricultural, and therapeutic applications. Central to this manipulation are three essential tools — cloning vectors, restriction endonucleases, and DNA ligase. Together, these molecular instruments form the backbone of recombinant DNA (rDNA) technology, … Read more
