In prokaryotes, the processes of transcription and translation are closely coupled, allowing translation to begin before transcription is fully completed. This is possible because prokaryotes lack a nuclear membrane, enabling ribosomes to access mRNA and start translating it into protein while the mRNA is still being synthesized.
