Study Notes
Transcription in Prokaryotes
- The sense strand of DNA has the same sequence as the mRNA in prokaryotes.
- Transcription occurs in the 5' to 3' direction in prokaryotes.
- Sigma factors play a crucial role in transcription initiation by recognizing specific DNA sequences and recruiting RNA polymerase to the transcription start site.
Transcription in Eukaryotes
- RNA polymerase II is responsible for transcription in eukaryotes.
Transcription Initiation
- Enhancers play a key role in transcription initiation by looping back to the promoter region, allowing transcription factors to bind and recruit RNA polymerase, thereby stimulating transcription.
