Many promoter regions contain CAAT boxes containing consensus
sequences CAAT or CCAAT approximately 70 to 80 bases upstream from
the transcription start site. How would you determine if this
region is important for transcription?
| a. |
Delete the CAAT box sequence and measure the transcription |
|
| b. |
Make mutations in the CAAT box sequence and measure the |
|
| c. |
Introduce extra CAAT box sequences and measure the transcription |
|
| d. |
All of the above would be good ways to determine the influence |
