Basis of differentiation | Eukaryotic promoters | Prokaryotic promoters |
Definition | Eukaryotic promoters are specific DNA sequences responsible for triggering the start of transcription in eukaryotic organisms | Prokaryotic promoters are DNA sequences that begin the process of transcription for genes in prokaryotic organisms. |
Promoters | The eukaryotic promoter includes several specific DNA elements such as the Pribnow box (also known as the TATA box), GC box, CAAT-box, and BRE | The prokaryotic promoter includes the -10 element, and the -35 elements |
Size of Distinct Structural Features | Larger upstream region | Shorter upstream region |
Overall bendability | Bendability may vary, and potentially be more flexible | Predicted to be less bendable |
Patterns of Transcription Regulation | Broader region of DNA surrounding the promoter | Localized structural elements near transcription start site |
