What is the difference between promoters of bacteria vs eukaryotes?
Promoter binding is very different in bacteria compared to eukaryotes. Eukaryotes require a minimum of seven transcription factors in order for RNA polymerase II (a eukaryote-specific RNA polymerase) to bind to a promoter. Transcription is tightly controlled in both bacteria and eukaryotes.
Do promoters differ between organisms?
The observed differences between the promoters from the two bacterial origins may be attributed to the differences in their mode of binding to their respective RNA polymerases (69–71).
What are the similarities and differences between origins and promoters?
Origin of replication is the site from where replication starts and promoter is the region from where transcription starts. Explanation: Origin of replication is present in the DNA and this is the site from where the replication of DNA starts.
Do prokaryotes have one promoter?
Prokaryotes only contain three different promoter elements: -10, -35 promoters, and upstream elements. These events do not occur in prokaryotes. mRNAs in prokaryotes tend to contain many different genes on a single mRNA meaning they are polycystronic.
What are the major differences in transcription between prokaryotes and eukaryotes?
Prokaryotic vs Eukaryotic Transcription
| Prokaryotic Transcription | Eukaryotic Transcription |
|---|---|
| Prokaryotic transcription occurs in the cytoplasm | Eukaryotic transcription occurs in the nucleus and translation occurs in the cytoplasm. |
| RNAs are released and processed in the cytoplasm | RNAs are released and processed in the nucleus |
Do eukaryotes have promoter?
Many eukaryotic genes have a conserved promoter sequence called the TATA box, located 25 to 35 base pairs upstream of the transcription start site. Transcription factors bind to the TATA box and initiate the formation of the RNA polymerase transcription complex, which promotes transcription.
What is a eukaryotic promoter?
Promoter sequences define the direction of transcription and indicate which DNA strand will be transcribed; this strand is known as the sense strand. Many eukaryotic genes have a conserved promoter sequence called the TATA box, located 25 to 35 base pairs upstream of the transcription start site.
Do eukaryotes have promoters?
What are the differences between prokaryotes and eukaryotes?
The difference between eukaryotic and prokaryotic cells is that eukaryotic cells are those which have a membrane-bound nucleus that contains genetic material, as well as organelles that are also membrane-bound. Whereas, prokaryotes are cells that don’t have a nucleus or membrane-encased…
What is found in both prokaryotes and eukaryotes?
A cell wall is a structure that is found on the outside of the plasma membrane that encloses the entire cell including the cell membrane. The cell wall in both eukaryotic and prokaryotic cells consists of a type of carbohydrate known as a polysaccharide.
How do prokaryotic and eukaryotic cells compare?
Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts , the cell wall, and the structure of chromosomal DNA.
Which cell is larger prokaryotic eukaryotic?
In general, the eukaryotic cells are bigger than the prokaryotic ones (10-100µm). Despite the wide variety of cells, they generally have the same structures. Each eukaryotic cell has a cell membrane, a nucleus, and a cytoplasm. The cell membrane is a universal cellular structure that is obligatory for all cell types.
