Question
Fill in the blank with either: enhancer, promoter, TFII transcription factor, or TS transcription factor. (Make sure to check your spelling.)
Genes can have multiple [1], but only one [2].
[3] are proteins that are located in every cell, regardless of cell type, and function to bind [4] to help recruit RNA Pol II.
There are also proteins that are important for cell-specific transcriptional regulation, and are expressed in very specific subsets of cells. These are called [5] and they bind to regulatory regions of DNA called [6].
[7] are regulatory regions of DNA that are always located immediately upstream of a gene, while [8] are regulatory regions of DNA that are not predictably located (they can be upstream, downstream, near or far).
