â¢ transcriptional regulation â controlling the rate of gene transcription for example by helping or hindering RNA polymerase binding to DNA. â¢ transcription â the process of making RNA from a DNA template by RNA polymerase.uch of the early understanding of transcription came from prokaryotic organisms, although the extent and complexity of transcriptional regulation is greater in eukaryotes. Prokaryotic transcription is governed by three main sequence elements:
