Answer:
Transcription factors.
Explanation:
Transcription and translation are the two important process involved in the gene expression of a particular protein. Transcription is the formation of RNA and translation is the formation of proteins.
Transcription requires different enzymes and transcription factors. Transcription factors are important factors that regulates the expression of transcription and may increase or decrease the process of transcription. Here, the protein that binds with dioxin acts as the transcription factors as it regulates the gene expression.
Thus, the correct answer is option (3).
<em>The temperature of the inner core is far above the melting point of iron. However, unlike the outer core, the inner core is not liquid or even molten. The inner core's intense pressure—the entire rest of the planet and its atmosphere—prevents the iron from melting.</em>
