Biology is the scientific study of life and living organisms. It examines structure, function, growth, origin, evolution, distribution, and interactions of living systems—from molecular machinery inside cells to planetary-scale ecosystems. As one of the core natural sciences, biology integrates chemistry, physics, mathematics, and computational methods to explain how life operates and evolves. Modern biology is […]
Allosteric regulation is a fundamental mechanism in biochemistry where a molecule binds to a protein at a site other than the active site, causing a conformational change that affects the protein’s activity. The term “allosteric” comes from the Greek words allos (other) and steros (site or space), emphasizing that the regulatory molecule binds to a

Overview DNA damage refers to structural alterations in the molecular architecture of deoxyribonucleic acid (DNA) that disrupt its normal chemical configuration. DNA encodes the genetic instructions necessary for cellular function, replication, and inheritance. When its structure is modified by physical, chemical, or biological agents, the integrity of genetic information is threatened. DNA damage occurs continuously
