Abstract

Genetic Regulation: Mechanisms Controlling Gene Expression in Living Systems

Author(s): Daniel K. Fischer

Genetic regulation refers to the mechanisms by which cells control the expression of genes, ensuring that the correct genes are activated or suppressed at appropriate times and locations. This regulation is essential for cellular differentiation, development, adaptation to environmental changes, and maintenance of homeostasis. Through coordinated control at transcriptional, post-transcriptional, translational, and post-translational levels, organisms achieve precise regulation of biological functions. This article provides an overview of genetic regulation, highlighting its fundamental mechanisms, biological significance, and role in health and disease. Advances in molecular biology have greatly enhanced understanding of genetic regulatory networks and their impact on cellular behavior.
