Answer:
The promoter region/sequence
Explanation:
Promoter sequences/region is where the transcription factors and RNA polymerase must attach before the gene can be transcribed. SO if we mutate this sequence, the transcription factors and RNA polymerase won't recognize it thus would not attach and transcribe the targeted gene.

Our central nervous system is made up of two tissues: the gray matter and the white matter. The gray matter is composed of the dendrites and the axon terminals where synapses are. These synapses are the links between neurons that transmits electrochemical signals. The white matter, on the other hand, is composed of axons that connect all the gray matter together. Therefore, the answer is: <span>white matter is primarily in the CNS in the presence of myelinated axons</span>
