DNA Binding to Osmy Promoter

Which DNA factors bind to the osmy promoter?

A. Neither

B. 038

C. 070

D. Both

Answer:

Both DNA factors 038 and 070 bind to the osmy promoter.

According to the results obtained from the polyacrylamide gel electrophoresis, it was observed that both DNA factors 038 and 070 bind to the osmy promoter. This conclusion was drawn by visualizing the radiolabeled bands on an x-ray film after separating the DNA fragments using gel electrophoresis. The presence of bands corresponding to both 038 and 070 indicates that both factors interact with the osmy promoter region.

Therefore, it can be concluded that both 038 and 070 act as transcription factors, binding to the osmy promoter to regulate gene expression.
