Therefore only basal transcription factor binds to the promoter for regulating transcription. Therefore the statement is false.

The second way is when the body’s normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, when this happens more often then not the tumor is usually cancerous.
