Gene expression is linked to RNA transcription, which cannot happen without RNA polymerase. However, this is where the similarities between prokaryote ... II can bind to a DNA sequence within ...

which in turn bind to regulatory sites in the DNA that effectively block RNA polymerase binding (Figure 3). The control of gene expression in eukaryotes is more complex than that in prokaryotes.

Prokaryotic cells are simpler and lack the eukaryote's membrane-bound organelles and nucleus, which encapsulate the cell's ...

Transcription initiation begins with the binding of RNA polymerase, a multi-subunit enzyme, to a specific DNA sequence called the promoter region. Prokaryotic promoters typically contain a Pribnow ...
