What region in eukaryotic genes usually contains the majority of regulatory elements such as GC and CAAT boxes?
A) 0 to 50
B) -50 to 0
C) -50 to -100
D) -100 to -150

The region -50 to -100 is known as the core promoter region and contains the majority of regulatory elements such as GC and CAAT boxes. The region upstream of -100 also contains regulatory elements but to a lesser extent. The region from 0 to 50 is the transcription start site and does not contain regulatory elements. The region from -50 to 0 is the proximal promoter region which contains some regulatory elements but not as many as the core promoter region. The region from -100 to -150 is further upstream of the core promoter region and may contain regulatory elements, but not as consistently as the core promoter region.
