What are the differences between the promoter region in prokaryotes and eukaryotes?
Posted April 5, 2024

Answer
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
