Regulation of Gene Expression: Operons, Epigenetics, and Transcription Factors

The video tutorial explores how cells regulate gene expression, starting with an introduction to transcription and translation. It delves into regulatory mechanisms, including feedback inhibition and operons in bacteria. The tutorial also covers positive and negative gene regulation, and complex regulation in eukaryotes, highlighting the role of transcription factors and histone modification.

Explain how signaling molecules can influence gene expression.

What are the implications of selective gene expression in cell specialization?

How do histone modifications affect gene expression?

What is the role of enhancers in gene regulation?
