Introduction to Molecular Biology

This topic provides a foundational overview of molecular biology, defining the field, its core molecules (DNA, RNA, genes, chromosomes, alleles), and its wide-ranging applications in science and medicine. Tailored for Zambian tertiary students beginning their studies in genetics, biotechnology, or biomedical sciences, the module introduces key concepts such as the central dogma, genetic code, gene expression, and molecular techniques like PCR, sequencing, and recombinant DNA technology. Learners will explore how molecular biology underpins paternity testing, forensic investigations, disease diagnosis, and agricultural improvement. A solid grasp of these basics is essential for progression in diploma or degree programs and for careers in laboratory science, research, or healthcare within Zambia. The topic sets the stage for advanced study, emphasizing the relevance of molecular biology to addressing health and economic challenges in Zambia through innovative scientific approaches.
