This textbook introduces biology as an interdisciplinary science, linking physics and chemistry to biological processes that operate within the laws of thermodynamics. Based on an evolutionary narrative, the focus is on the molecular composition and the biochemistry of cells. By grounding biology in its molecular foundations, this approach reveals unifying principles underlying life's diversity and provides a conceptual framework for biological complexity. Core concepts include macromolecular structure and function, information encoding and decoding, and universal principles of energy conversion.
