Can bacteria do transcription and translation?
In bacteria, transcription and translation can occur simultaneously in the cytoplasm of the cell, whereas in eukaryotes transcription occurs in the nucleus and translation occurs in the cytoplasm.
Why are transcription and translation coupled in bacteria?
Bacteria depend on transcription-translation coupling for genome integrity, termination of transcription and control of mRNA stability. Consequently, artificial disruption of transcription-translation coupling impairs the fitness of bacteria.
Are transcription and translation coupled in bacteria?
Just when you thought the fundamental processes of gene transcription and translation could offer no more surprises, researchers report that RNA polymerase and the ribosome, the macromolecules responsible for transcription and translation, respectively, can be physically coupled in bacteria.
Where does translation occur in bacteria?
cytosol
In prokaryotes (bacteria and archaea), translation occurs in the cytosol, where the large and small subunits of the ribosome bind to the mRNA. In eukaryotes, translation occurs in the cytoplasm or across the membrane of the endoplasmic reticulum in a process called co-translational translocation.
Where does transcription and translation occur in a cell?
1 Answer. Transcription occurs in the nucleus, whereas translation occurs in the cytoplasm.
How are transcription and translation different in prokaryotes and eukaryotes?
The prokaryotic process of transcription takes place in the cytoplasm. There is no nucleus in it, whereas in eukaryotic, the process takes place in the nucleus. The process between transcription and protein synthesis are coupled in prokaryotic, whereas in eukaryotic, transcription and protein synthesis are not coupled.
Where in the cell does translation occur?
the ribosome
Where Translation Occurs. Within all cells, the translation machinery resides within a specialized organelle called the ribosome. In eukaryotes, mature mRNA molecules must leave the nucleus and travel to the cytoplasm, where the ribosomes are located.
How does translation happen in a cell?
Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins. The ribosome has a small and a large subunit and is a complex molecule composed of several ribosomal RNA molecules and a number of proteins.
Where does transcription occur in prokaryotes?
The prokaryotes, which include bacteria and archaea, lack membrane-bound nuclei and other organelles, and transcription occurs in the cytoplasm of the cell.
How is transcription similar in bacteria and eukaryotes?
While specific aspects of transcription differ between prokaryotes and eukaryotes, the basic chemistry behind the process is the same. Both utilize RNA polymerase to catalyze the synthesis of RNA, and while regulation may differ, the ultimate product of transcription in prokaryotes and eukaryotes is RNA.
