How is the process of mRNA Transcription different in prokaryotes vs 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.
Is mRNA eukaryotic or prokaryotic?
| Prokaryotic vs Eukaryotic mRNA | |
|---|---|
| Prokaryotic mRNA is the RNA molecule which codes for prokaryotic proteins. | Eukaryotic mRNA is the RNA molecule which encodes for eukaryotic proteins. |
| Type | |
| Prokaryotic mRNA is polycistronic. | Eukaryotic mRNA is monocistronic. |

What is the difference between prokaryotic and eukaryotic transcription?
These were a few differences between prokaryotic and eukaryotic transcription….Prokaryotic vs Eukaryotic Transcription.
| Prokaryotic Transcription | Eukaryotic Transcription |
|---|---|
| Doesn’t require any proteins or other factors for the initiation of transcription | Requires proteins known as transcription factors for the initiation. |
Does prokaryotic mRNA have a 5 cap?
In eukaryotes, the 5′ end of the mRNA is protected from 5′ to 3′ exonucleolytic activity by the presence of the 5′ cap structure. In prokaryotes, the 5′ end of the newly transcribed mRNA is not further modified and retains the 5′ triphosphate.
Why is eukaryotic mRNA more stable than prokaryotic mRNA?
18 Eukaryotic RNA Processing Eukaryotic mRNAs must undergo several processing steps before they can be transferred from the nucleus to the cytoplasm and translated into a protein. The additional steps involved in eukaryotic mRNA maturation create a molecule that is much more stable than a prokaryotic mRNA.
Is mRNA Monocistronic in prokaryotes?
mRNA is polycistronic in eukaryotes and monocistronic in prokaryotes.
What are the major differences between prokaryotic and eukaryotic cells?
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.
Does prokaryotic mRNA have poly A tail?
The poly(A) tail is important for the nuclear export, translation and stability of mRNA. mRNA molecules in both prokaryotes and eukaryotes have polyadenylated 3′-ends, with the prokaryotic poly(A) tails generally shorter and less mRNA molecules polyadenylated.
Why do prokaryotes not need a 5 cap?
Once in place, the cap plays a role in the ribosomal recognition of messenger RNA during translation into a protein. Prokaryotes do not have a similar cap because they use other signals for recognition by the ribosome.
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…
Is RNA prokaryotic or eukaryotic?
Although both prokaryotic and eukaryotic cells have the same DNA in terms of molecular structure; there are some differences in how the DNA is packaged and replicated (copied) in prokaryotic versus eukaryotic cells. RNA ( ribonucleic acid ) is involved in translating the genetic code into proteins.
What do eukaryotes usually contain?
an organism of the Eucaryotae, whose cells (eukaryotic cells) have a true nucleus that is bounded by a nuclear membrane, contains the chromosomes, and divides by mitosis. Eukaryotic cells also contain membrane-bound organelles, such as mitochondria, chloroplasts, lysosomes, and the Golgi apparatus.
Do prokaryotes have mitochondria?
No, prokaryotes do not have mitochondria. Mitochondria are only found in eukaryotic cells. This is also true of other membrane-bound structures like the nucleus and the Golgi apparatus (more on these later). One theory for eukaryotic evolution hypothesizes that mitochondria were first prokaryotic cells that lived inside other cells.
