The termination of transcription is different for the three different eukaryotic RNA polymerases. This releases the upstream portion of the transcript, which will serve as the initial RNA prior to further processing the pre-mRNA in the case of protein-encoding genes. In the case of protein-encoding genes, a protein complex will bind to two locations on the growing pre-mRNA once the RNA Polymerase has transcribed past the end of the gene.

This terminates transcription at some random location downstream from the true end of the gene bottom figure. Privacy Policy. Skip to main content. Genes and Proteins. Search for:. Eukaryotic Transcription. Initiation of Transcription in Eukaryotes Initiation is the first step of eukaryotic transcription and requires RNAP and several transcription factors to proceed.

Key Takeaways Key Points Eukaryotic transcription is carried out in the nucleus of the cell and proceeds in three sequential stages: initiation, elongation, and termination.
