Differbetween
The main difference between prokaryotic and eukaryotic mRNA is that prokaryotic mRNA is polycistronic, whereas eukaryotic mRNA is monocistronic. ... In addition to these, transcription is coupled with translation in prokaryotes while transcription of eukaryotes occurs after the completion of transcription.

What does prokaryotic mRNA have that eukaryotic mRNA doesn t?
The mRNAs found in prokaryotes differ from that of eukaryotes in the following ways: ... Therefore, an mRNA molecule synthesizes more than one polypeptide chains. On the other hand, the mRNAs of eukaryotes are monocistronic i.e. contain only a single initiation and termination codons and synthesize one chain only.
How does the synthesis of mRNA differ in prokaryotes and eukaryotes?
In most of the bacterial cells translation of the mRNA begins while the mRNA is still being transcribed from the DNA molecule. Whereas in eukaryotes the mRNA produced from DNA template are first transported into the cytoplasm via nuclear pores, then it forms complexes with ribosome, then the protein are synthesized.
What are the differences 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. |
Do prokaryotes have mRNA?
During its life, an mRNA molecule may also be processed, edited, and transported prior to translation. Eukaryotic mRNA molecules often require extensive processing and transport, while prokaryotic mRNA molecules do not. A molecule of eukaryotic mRNA and the proteins surrounding it are together called a messenger RNP.
Is uracil a prokaryote?
Bacterial DNA contains uracil instead of thymine. The four bases contained in all organisms' DNA are adenine, thymine, cytosine, and guanine. Uracil is a base that replaces thymine in RNA. Uracil is not present in the DNA of bacteria.
Where is mRNA found in eukaryotic cells?
The process of making mRNA from DNA is called transcription, and it occurs in the nucleus. The mRNA directs the synthesis of proteins, which occurs in the cytoplasm. mRNA formed in the nucleus is transported out of the nucleus and into the cytoplasm where it attaches to the ribosomes.
What is the difference between protein synthesis in prokaryotes and eukaryotes?
A few aspects of protein synthesis are actually less complex in eukaryotes. In prokaryotes, mRNA is polycistronic and may carry several genes that are translated to give several proteins. In eukaryotes, each mRNA is monocistronic and carries only a single gene, which is translated into a single protein.
What is the difference between ribosomes in prokaryotes and eukaryotes?
In prokaryotes, ribosomes include three separate rRNA molecules, whereas in eukaryotes ribosomes include four separate rRNA molecules. Ribosomes consist of a large subunit and a small subunit. ... In contrast, prokaryotic cells contain ribosomes reaching 70S, split into 30S and 50S subunits.
Is protein synthesis faster in prokaryotes or eukaryotes?
Explanation: Prokaryotic protein synthesis can be fairly fast because one gene can be transcribed and translated simultaneously. Eukaryotic synthesis is slower, but more precious. They can "check" the mRNA before it is translated into protein.
What are two major differences between transcription in prokaryotes and in 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 are the steps of eukaryotic transcription?
Key Points
- Eukaryotic transcription is carried out in the nucleus of the cell and proceeds in three sequential stages: initiation, elongation, and termination.
- Eukaryotes require transcription factors to first bind to the promoter region and then help recruit the appropriate polymerase.
Are prokaryotes bacteria?
Bacteria. Bacteria are microorganisms made up of a single prokaryotic cell. There are two general categories of cells: prokaryotic and eukaryotic. Sometimes, organisms are referred to as prokaryotes or eukaryotes, based on the type of cell(s) that compose them.
