How do prokaryotes control gene expression?
Just so, what is gene expression in prokaryotes?
Prokaryotic gene expression (both transcription and translation) occurs within the cytoplasm of a cell due to the lack of a defined nucleus; thus, the DNA is freely located within the cytoplasm. Eukaryotic gene expression occurs in both the nucleus (transcription) and cytoplasm (translation).
Furthermore, how is gene expression controlled in prokaryotes quizlet? Transcription, translation or post-translation. Negative control occurs when a regulatory protein prevents transcription. Positive control occurs when a regulatory protein increases the transcription rate.
Regarding this, what mechanisms does a prokaryotic cell use to control gene expression?
Prokaryotes regulate gene expression by controlling the amount of transcription, whereas eukaryotic control is much more complex.
How do you control gene expression?
Mechanisms of gene regulation include:
- Regulating the rate of transcription.
- Regulating the processing of RNA molecules, including alternative splicing to produce more than one protein product from a single gene.
- Regulating the stability of mRNA molecules.
- Regulating the rate of translation.
