In the negative a repressor protein binds to an operator and prevents a gene to be expressed.Figure 1. In prokaryotes, structural genes of related function are often organized together on the genome and transcribed together under the control of a single promoter. The operon’s regulatory region includes both the promoter and the operator. If a repressor binds to the operator, then the structural genes will not be transcribed.Control of Gene Expression in Prokaryotes 151 Control of Gene Expression in Prokaryotes How do prokaryotes use operons to control gene expression?

Correct Answer. D. Transcriptional control. Explanation. Transcriptional control is the most common form of gene expression control in both prokaryotic and eukaryotic organisms. This process involves the regulation of gene expression at the level of transcription, where the DNA sequence is transcribed into RNA.

In the case of E. coli, the corepressor is the Tryptophan. question.Transcriptional Regulation of Gene Expression in Prokaryotes: Gene transcription is regulated in bacteria through a complex of genes termed operon. These are transcriptional units in which several genes, with related functions, are regulated together. Other genes also occur in operons which encode regulatory proteins that control gene expression.Likewise, prokaryotic cells can turn genes on and off based on environmental factors. Sometimes related genes are grouped together with one switch. This group of genes, along with the sections of DNA that regulate them, is called an operon. Control of Gene Expression in Prokaryotes DNA regulation controls gene expression in cells, allowing different cell types to perform unique functions despite having the same DNA. Prokaryotes ...For bacteria, the initiation of transcription is the most important point of control. Transcription regulator proteins bind short stretches of DNA called regulatory DNA sequences. Transcription regulators bind to regulatory DNA sequences close to where RNApol binds. Binding can activate or repress gene (s) transcription.Regulation of Gene Expression in Prokaryotes.
