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 ...

RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription. As complex molecule composed of protein subunits, RNA ...

This process of protein synthesis occurs in two stages - transcription and translation ... by an enzyme (helicase enzyme). The enzyme RNA polymerase attaches to the DNA in a non-coding region ...
