Final answer:
Translation in prokaryotes occurs in the cytoplasm concurrently with transcription, allowing for a quick response to environmental cues. In eukaryotes, transcription happens in the nucleus and is separated from translation which occurs in the cytoplasm, with mRNA processing required before translation.
Step-by-step explanation:
The process of translation in prokaryotes is different from that in eukaryotes in several important ways. Notably, in prokaryotes, transcription and translation can occur concurrently because both processes take place in the cytoplasm. This coupling allows for a rapid response to environmental changes as ribosomes can begin translating an mRNA molecule as soon as a portion of it is transcribed, even before transcription is complete.
In contrast, eukaryotes exhibit a spatial separation between transcription and translation; transcription occurs inside the nucleus while translation takes place in the cytoplasm. Additionally, eukaryotic mRNA undergoes extensive processing, including capping, splicing, and polyadenylation, before it is exported out of the nucleus to be translated by ribosomes.
This separation and post-transcriptional mRNA processing result in a delay between the two processes in eukaryotes. Moreover, eukaryotic mRNAs are typically monogenic, meaning they code for a single protein, whereas prokaryotic mRNAs can be polycistronic, containing information for several proteins. Understanding this key difference is crucial for studying genetic expression and regulation within these two domains of life.
