Regulation of Gene Expression — Operons, Epigenetics, and Noncoding RNAs Explained | Chapter 18 of Campbell Biology
Regulation of Gene Expression — Operons, Epigenetics, and Noncoding RNAs Explained | Chapter 18 of Campbell Biology Welcome to Last Minute Lecture! This post explores the complex world of gene expression regulation, as presented in Chapter 18 of Campbell Biology . Learn how prokaryotic and eukaryotic cells control gene activity through operons, epigenetic modifications, transcription factors, and noncoding RNAs.

Introduction: Why Regulating Gene Expression Matters Gene regulation ensures that the right genes are expressed at the right time, allowing cells to respond to environmental changes, specialize for different functions, and properly develop from a single fertilized egg. Misregulation can result in diseases like cancer. Gene Regulation in Prokaryotes: The Operon Model Operons: Groups of bacterial genes regulated together under a single promoter. Examples...
