The correct answer is:

D). It cannot attach to the promoter.

Explanation:

It cannot attach to the promoter. Only the proteins that the bacteria Escherichia coli (E. coli) needs are integrated at any given time. A transcription factor can operate as a transcription activator as strong as a transcription repressor. The same transcription factor can work as a repressor for a group of genes and activator for another group. Such function has temporary and/or spatial specificity. A number of oncogenes are transcriptional activators during early development but repressor through adulthood, their strange expression drives to cell proliferation and tumor development/oncogenesis.
