Answer
Gene expression in prokaryotes is often quicker than in eukaryotes due to the lack of a nuclear envelope.
Solution
a
Lack of nuclear envelope: Prokaryotic cells do not have a nuclear envelope, which allows for simultaneous transcription and translation
Key Concept
Coupled transcription and translation
Explanation
In prokaryotes, the absence of a nuclear envelope means that mRNA can be translated by ribosomes directly after it is transcribed from DNA, without the need for RNA processing and transport. This proximity of transcription and translation machinery speeds up gene expression.
