Molecular Biology is a course that focuses on the molecular mechanisms that govern the structure, function, and regulation of genes and proteins in living organisms. It explores DNA replication, transcription, translation, gene expression, genetic engineering, and cell signaling. The course combines elements of genetics, biochemistry, and cell biology, with practical laboratory work involving techniques like PCR, gel electrophoresis, cloning, and DNA sequencing. Molecular Biology is essential for careers in biomedical research, biotechnology, medicine, pharmaceuticals, and genetic counseling.
