What are the differences between prokaryotic and eukaryotic gene regulation?
Gene expression in prokaryotes is mostly regulated at the transcriptional level (some epigenetic and post-translational regulation is also present), whereas in eukaryotic cells, gene expression is regulated at the epigenetic, transcriptional, post-transcriptional, translational, and post-translational levels.
Why is there such a difference between prokaryotic and eukaryotic gene regulation?
The main difference between prokaryotic and eukaryotic gene expression is that the entire prokaryotic gene expression occurs in the cytoplasm whereas a part of the eukaryotic gene expression occurs inside the nucleus while rest occurs in the cytoplasm.
What is the main difference between prokaryotic and eukaryotic gene regulation quizlet?
What is the main difference between eukaryotic and prokaryotic gene regulation? Groups of eukaryotic genes are likely to be regulated together, whereas each prokaryotic gene is usually regulated separately.
What is the difference between eukaryotic and prokaryotic gene transcription quizlet?
In a eukaryotic cell, transcription occurs in the nucleus, and translation occurs in the cytoplasm. In a prokaryotic cell, transcription and translation are coupled; that is, translation begins while the mRNA is still being synthesized.
What is gene regulation in prokaryotes?
The regulation of gene expression in prokaryotic cells occurs at the transcriptional level. There are two majors kinds of proteins that control prokaryotic transcription: repressors and activators. Repressors bind to an operator region to block the action of RNA polymerase.
How is gene regulation in prokaryotes and eukaryotes similar?
In both prokaryotes and eukaryotes, the gene expression is regulated at the transcriptional level. Both mechanisms are controlled by transcription factors, activators, and repressors. Both prokaryotic and eukaryotic genes can be regulated to produce multiple gene products.
What are two major differences between transcription in prokaryotic and eukaryotic cells?
Main Difference – Prokaryotic vs. Eukaryotic Transcription. Prokaryotic transcription occurs in the cell cytoplasm and, in prokaryotes, both transcription and translation happen simultaneously. Eukaryotic transcription occurs in the cell nucleus and, in eukaryotes, transcription and translation differ in space and time …
Where are there differences in transcription between prokaryotes and eukaryotes?
There is no such structure seen in prokaryotes. Another main difference between the two is that transcription and translation occurs simultaneously in prokaryotes and in eukaryotes the RNA is first transcribed in the nucleus and then translated in the cytoplasm.
What is gene regulation in eukaryotes?
Gene regulation is the process of controlling which genes in a cell’s DNA are expressed (used to make a functional product such as a protein). Different cells in a multicellular organism may express very different sets of genes, even though they contain the same DNA.
How are genes regulated in eukaryotes?
Gene expression in eukaryotic cells is regulated by repressors as well as by transcriptional activators. Like their prokaryotic counterparts, eukaryotic repressors bind to specific DNA sequences and inhibit transcription.
How are genes regulated in prokaryotes?
What is one way that gene regulation in eukaryotic and prokaryotic cells is similar?
One way that gene regulation in eukaryotic and prokaryotic cells is similar is: In both types of cell, the primary mechanism to regulate gene expression is at the level of transcriptional regulation.
What are the differences between eukaryotes and prokaryotes in regards to how they store genetic material?
There are several differences between the two, but the biggest distinction between them is that eukaryotic cells have a distinct nucleus containing the cell’s genetic material, while prokaryotic cells don’t have a nucleus and have free-floating genetic material instead.
