Question
Eukaryotes need to regulate their genes
- During cell specialization that occurs during development
- In order to maintain homeostasis
- Both a and b
- Neither a nor b
Hint:
Eukaryotes need to regulate their genes it is done through protein synthesis.
The correct answer is: Both a and b
- Transcription in eukaryotic cells is controlled by proteins that bind to specific regulatory sequences and modulate the activity of RNA polymerase.
- The intricate task of regulating gene expression in the many differentiated cell types of multicellular organisms is accomplished primarily by the combined actions of multiple different transcriptional regulatory proteins. In addition, the packaging of DNA into chromatin and its modification by methylation impart further levels of complexity to the control of eukaryotic gene expression. In order to maintain cell specialization that occurs during development and in order to manti homeostasis.
