Molecular Cloning and Vector Systems

Molecular Cloning is a core technique in genetic engineering that involves inserting a DNA fragment into a vector, transforming it into a host cell, and generating multiple copies. This topic covers various vector systems including plasmids, bacteriophages (lambda, M13), cosmids, and bacterial artificial chromosomes (BACs), each suited for different insert sizes and applications. Zambian tertiary students learn key steps: restriction digestion, ligation, transformation, selection, and screening. Applications range from gene expression and protein production to functional studies and therapeutic development (e.g., recombinant insulin). Mastery of cloning principles is essential for Zambian university learners pursuing careers in biotechnology, pharmaceutical sciences, and research, enabling them to contribute to local biomanufacturing, vaccine development, and genetic technology advancement.
