Physiology, as a component of Genomics within Zoology and Science, focuses on the functioning of organisms at various levels, from cells to whole organisms. It explores how genetic information influences the physiological processes that underpin an organism's survival and reproduction. This includes studying the regulation of gene expression, protein synthesis, and cell signaling pathways, as well as the integration of these processes into complex systems such as organs and organ systems. Physiology in this context thus provides a functional perspective on the genetic information encoded in an organism's genome, allowing for a more comprehensive understanding of how genes contribute to phenotypic traits and organismal function.
