Gene regulation differs between prokaryotes and eukaryotes in a few ways. Show There are multiple ways gene regulation differs between prokaryotes and eukaryotes. Prokaryotics don't have a nucleus but eukaryotics do (see image below).
Posted August 11, 2022Prokaryotic organisms are single-celled organisms that do not have a defined nucleus. Their DNA floats freely within the cell cytoplasm. Eukaryotic cells are more complex. They have intracellular organelles and their DNA is contained inside the cell’s nucleus where it is transcribed into RNA. Prokaryotic and eukaryotic gene expression are two processes involved in the transcription of genes. These are the key differences between the two processes:

Central Dogma & Gene Regulation 1 conceptReview of Prokaryotic vs. Eukaryotic Gene Expression 5m Play a video: There are a variety of sigma factors that affect transcription. Sigma factors are parts of RNA polymerase that recognize promoter regions. It occurs in the nucleus. Termination occurs when a stem-loop is formed or due to the presence of Rho protein. The prokaryotic mRNA does not include introns & does not need to be processed. Eukaryotes have monocistronic mRNA while prokaryotes can have polycistronic mRNA. Eukaryotic transcription occurs in the nucleus, while prokaryotic transcription occurs in the cytoplasm. Eukaryotes use transcription factor proteins in transcription, while prokaryotes use sigma factors. Simultaneous transcription and translation occur in prokaryotes but not eukaryotes. All of the above are major differences between eukaryotic and prokaryotic transcription. Because in prokaryotes, transcription and translation both occur in the cytoplasm. Because in eukaryotes, transcription and translation do not occur in the same location within the cell. Because prokaryotes have polycistronic mRNA while eukaryotes have monocistronic mRNA. Because prokaryotes use sigma factors while eukaryotes use transcription factors. What is the difference between eukaryote and prokaryote gene expression?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).
How is eukaryotic gene expression different from prokaryotic gene expression quizlet?Eukaryotes regulate gene expression through the use of protein transcription factors whereas prokaryotes do not. Eukaryotes regulate gene expression primarily post-transcriptionally, whereas prokaryotes primarily regulate transcription.
How is gene expression in prokaryotes and eukaryotes similar?How are Prokaryotic and Eukaryotic Gene Expression similar? Both require the participation of regulatory proteins, some of which (transcription factors) attach directly to DNA sequences. eukaryotes: activator proteins act on enhancer DNA sequences; repressor proteins act on silencer DNA sequences.
Why is gene expression faster in prokaryotes than in eukaryotes?When more protein is required, more transcription occurs. Therefore, in prokaryotic cells, the control of gene expression is almost entirely at the transcriptional level. Eukaryotic cells, in contrast, have intracellular organelles and are much more complex.
