In eukaryotes, transcription occurs in the nucleus. RNA polymerase II transcribes the DNA forming an mRNA transcript.
The mRNA is then modified. It has a 5'-cap and a 3'polyA tail and it can also be spliced and edited by various enzymes. Once an mRNA molecule has been correctly edited it is exported out of the nucleus through nuclear pores. Once in the cytoplasm can be localized to different compartments of the cell, but most of the protein synthesis occurs on the rough ER.
Here various translation factors help ribosomes to translate the DNA into protein. Translation occurs in the cytoplasm.
Do not get this confused with prokaryotes. In prokaryotes, they do not have organelles and so transcription and translation are coupled in the cytoplasm... (they occur at the same time).
Pre-mRNA is produced in the nucleus of the cell during the process of transcription. In eukaryotic cells, DNA is transcribed into pre-mRNA, which then undergoes processing to become mature mRNA before it is transported to the cytoplasm for translation.
In a eukaryotic cell, RNA is primarily synthesized in the nucleus. The process of transcription occurs there, where DNA is used as a template to produce messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). After synthesis, the RNA molecules undergo processing before they are transported to the cytoplasm for translation and other functions.
Protein synthesis differs in prokaryotes and eukaryotes primarily due to cellular structure and compartmentalization. In prokaryotes, transcription and translation occur simultaneously in the cytoplasm since they lack a defined nucleus. In contrast, eukaryotes have a nucleus where transcription occurs, followed by RNA processing before translation takes place in the cytoplasm. Additionally, eukaryotic mRNA undergoes modifications like capping and polyadenylation, which are not present in prokaryotic mRNA.
Transcription is the process by which genetic information from DNA is copied into messenger RNA (mRNA). This occurs in the nucleus of eukaryotic cells, where RNA polymerase enzyme binds to a specific region of the DNA and synthesizes the mRNA strand complementary to the DNA template. Once synthesized, the mRNA then undergoes processing before being transported to the cytoplasm for translation into proteins. In prokaryotic cells, transcription occurs in the cytoplasm, as they lack a defined nucleus.
Protein synthesis differs in prokaryotes and eukaryotes primarily due to their cellular structures. In prokaryotes, transcription and translation occur simultaneously in the cytoplasm, as they lack a defined nucleus. In contrast, eukaryotes have a compartmentalized structure where transcription occurs in the nucleus and translation takes place in the cytoplasm, allowing for additional processing of mRNA before it is translated. These differences reflect the complexity of eukaryotic cells compared to prokaryotic cells.
Bacterial translation occurs in the cytoplasm and has fewer post-translational modifications. Eukaryotic translation occurs in the cytoplasm and on the endoplasmic reticulum, and involves more complex regulatory mechanisms and additional processing steps.
In prokaryotes, transcription occurs in the cytoplasm since they lack a nucleus, while in eukaryotes, transcription occurs in the nucleus. Prokaryotic transcription is often coupled with translation, meaning ribosomes can start translating mRNA even before transcription is complete, whereas in eukaryotes, transcription and translation are spatially and temporally separated. Prokaryotic mRNA does not typically undergo extensive processing (such as splicing or capping) after transcription, whereas eukaryotic mRNA is extensively processed before being translated.
Transcription takes place in the nucleus of eukaryotic cells.
Gene expression can be controlled at any of several stages, which we divide broadly into transcription, processing and translation. Transcription often is controlled at the stage of initiation, or at termination but usually not controlled at elongation. In eukaryotic cells, processing of the RNA product may be regulated at the stages of modification, splicing, transport, or stability. Translation may be regulated, usually at the stages of initation and termination just like transcription. Gene expression can be controlled at any of several stages, as during transcription, processing and translation. Transcription often regulated at initiation and termination but elongation is usually not regulated. In eukaryotes cells, processing of the RNA product may be regulated at the stages of modification, splicing, transport, or at stability. Translation may be regulated at initiation and termination just like transcription.
Pre-mRNA is produced in the nucleus of the cell during the process of transcription. In eukaryotic cells, DNA is transcribed into pre-mRNA, which then undergoes processing to become mature mRNA before it is transported to the cytoplasm for translation.
In eukaryotic cells, you have a nucleus, whereas with prokaryotic cells you have none and you are missing some organelles found with the eukaryotes. Eukaryotes organelles are found within the cytoplasm.
In a eukaryotic cell, RNA is primarily synthesized in the nucleus. The process of transcription occurs there, where DNA is used as a template to produce messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). After synthesis, the RNA molecules undergo processing before they are transported to the cytoplasm for translation and other functions.

After transcription is completed, RNA goes through a process called RNA processing, where it is modified and prepared for translation. The processed RNA then leaves the nucleus and enters the cytoplasm, where it can be used to make proteins during translation.
