Question
Which of the following is incorrect concerning binding sites on the activator?
An activator can cause chromatin remodeling around a promoter.
An inducer binds to the activator to change its shape and permit DNA binding.
A co-activator binds to the allosteric site and guides the activator to the DNA.
A repressor binds to the activator to stop it from activating transcription.
The activator binds to the DNA using a functional domain.
A.An activator can cause chromatin remodeling around a promoter.
B.An inducer binds to the activator to change its shape and permit DNA binding.
C.A co-activator binds to the allosteric site and guides the activator to the DNA.
D.A repressor binds to the activator to stop it from activating transcription.
E.The activator binds to the DNA using a functional domain.
Explanation / Answer
D
repressor binds to DNA at the operator region so that RNA polymerase cannot bind to promoter and thereby inhibts transcription. A repressor would not bind to activator.
