Biochemistry is the study of the chemical processes and substances that occur within living organisms. It focuses on the structure, function, and interactions of biological molecules such as proteins, nucleic acids, carbohydrates, and lipids. Biotechnology, on the other hand, involves the use of living organisms or their components to develop products and processes for various applications, such as medicine, agriculture, and industry. It often involves genetic engineering, fermentation, and other techniques to manipulate biological systems. Molecular biology is a branch of biology that focuses on the structure and function of macromolecules essential to life, such as DNA, RNA, and proteins. It seeks to understand the molecular basis of biological processes and often involves techniques such as DNA sequencing, cloning, and gene expression analysis. **
