How Do Chromatin- Remodeling Complexes Recognize the Genes They Should

Question

How do chromatin- remodeling complexes recognize the genes they should act on?
A) Chromatin- remodeling complexes recognize specific transcription factors bound to regulatory sequences of DNA.
B) Chromatin- remodeling complexes bind to the basal transcription complex.
C) Chromatin- remodeling complexes are activated by specific extracellular signals that direct them to particular genes.
D) Chromatin- remodeling complexes recognize specific promoters when they are phosphorylated, methylated, or acetylated.

Accepted Answer

Chromatin-remodeling complexes recognize specific transcription factors bound to regulatory sequences of DNA, which then recruit the chromatin-remodeling complexes to the appropriate genes. This allows for fine control over gene expression, as only the genes with the appropriate transcription factors will be affected by the chromatin-remodeling complexes.
