3. Regulation of Gene Expression in Eukaryotes

Transcriptionally Active Chromatin Is Structurally Distinct from Inactive Chromatin

Most Eukaryotic Promoters Are Positively Regulated

DNA-Binding Activators and Coactivators Facilitate Assembly of the Basal Transcription Factors

The Genes of Galactose Metabolism in Yeast Are Subject to Both Positive and Negative Regulation

Transcription Activators Have a Modular Structure

Eukaryotic Gene Expression Can Be Regulated by Intercellular and Intracellular Signals

Regulation Can Result from Phosphorylation of Nuclear Transcription Factors

Many Eukaryotic mRNAs Are Subject to Translational Repression

Posttranscriptional Gene Silencing Is Mediated by RNA Interference

RNA-Mediated Regulation of Gene Expression Takes Many Forms in Eukaryotes

Development Is Controlled by Cascades of Regulatory Proteins

Stem Cells Have Developmental Potential That Can Be Controlled
