Abstract

Mutations are essential biological events that influence genetic diversity, evolutionary processes, and the development of various diseases. They are defined as heritable alterations in the DNA sequence that may occur spontaneously or be induced by environmental mutagens. This article provides a comprehensive analysis of the main types of mutations, their underlying molecular mechanisms, and their biological consequences at the cellular, organismal, and population levels. Using a qualitative review of contemporary scientific literature, mutations are classified according to their origin, structural characteristics, and functional effects. The results demonstrate that while neutral and beneficial mutations contribute to genetic variability and evolutionary adaptation, deleterious mutations are closely associated with inherited genetic disorders, metabolic diseases, and cancer. The discussion emphasizes the dual role of mutations as both drivers of evolution and major factors in disease development. Understanding mutation mechanisms and outcomes is crucial for advances in molecular biology, medical genetics, and personalized medicine.
