What type of regulatory transcription factor binds DNA in order to increases the transcription of a gene?

B)a repressor exerting positive control
C)an activator exerting negative control
D)an activator exerting positive control
E)a combination of both a repressor and activator exerting negative control

An activator exerting positive control binds DNA in order to increase the transcription of a gene. Activators are transcription factors that bind to specific DNA sequences, called enhancers, and help recruit RNA polymerase to the gene promoter, leading to increased transcription. Positive control means that the activator enhances or increases transcription, as opposed to negative control where a repressor inhibits or decreases transcription.
