Gene expression is linked to RNA transcription, which cannot happen without RNA polymerase. However, this is where the similarities between prokaryote and eukaryote expression end. Central to the ...

This image illustrates the process of gene transcription within a cell. The DNA double helix unwinds to expose a specific sequence, allowing RNA polymerase to synthesize a complementary pre-mRNA ...

Also, as the prokaryotic cell lacks a clearly defined nucleus and both transcription and translation takes place in the cytoplasm, there is no need to transport the mRNA to the cytoplasm after ...
