Protein X activates gene expression only in cells exposed to a specific signaling molecule. In a study,
researchers determined the intracellular location of Protein X in cultured cells both before and after exposing
the cells to the signaling molecule. The results of the study are shown in the diagram.

Based on the results, which of the following best describes what Protein X is a transcription factor.

What are transcription factors?

Transcription factors are proteins that contain at least two functional domains: one binding with DNA and the other binding with RNA polymerase. These proteins control when, where and how the genes will be transcribed, being the basis for the control of gene expression.

In this case the protein X is a transcription factor which means proteins that help turn specific genes "on" or "off" by connecting to nearby DNA. Transcription factors that are activators drive the transcription of a gene.
