Biological mechanisms refer to the processes and systems within living organisms that regulate various functions and responses. This research area focuses on understanding how these mechanisms operate at a cellular, molecular, and physiological level, and how they contribute to the overall function and behavior of organisms. Researchers in this field study topics such as gene expression, protein interactions, signaling pathways, and metabolic processes to uncover the underlying biological processes that drive health, disease, and evolution. By investigating these mechanisms, researchers can gain insights into how living organisms function and develop new strategies for treating diseases and improving human health.
