Molecular biology is an interdisciplinary field of science that studies the structure, function, and behavior of biological molecules, particularly those that carry genetic information (DNA and RNA) and the proteins that interact with them. It combines concepts and techniques from biology, chemistry, and physics to understand the complex processes involved in cellular function, including gene expression, protein synthesis, DNA replication, and genetic regulation. Molecular biology has revolutionized our understanding of biology and has led to significant advances and innovations in fields such as medicine, agriculture, and biotechnology.
Molecular biology of the cell involves different macromolecules or biomolecules like proteins, carbohydrates, lipids, DNA and RNA (nucleic acids) and amino acids. It focuses on studying their chemical and physical structures, compositions, modification, mechanisms, interactions, and functions which are essential and vital to life processes.
