Regulation of Gene Expression: Strategies and Mechanisms

Explore the intricate mechanisms of gene expression regulation, from transcription factors to epigenetic changes and alternative splicing. Understand the control of gene activity in different organisms, including viruses and bacteria. This comprehensive guide covers positive and negative regulation, metabolic pathway control, operon systems, transcription initiation, DNA methylation, X chromosome inactivation, and more.
