Control of Gene Expression in Eukaryotes

Control of Gene Expression in Eukaryotes

Levels of Control

• Gene expression in eukaryotes is controlled at multiple levels.
  • Protein structure.
  • Transcription initiation.

Chromatin Structure and Transcription

• Transcription depends on the accessibility of DNA to RNA polymerase and other proteins.
• Extended chromatin structure is more accessible for transcription than condensed structures.
