Trans- Acting Regulators of Gene Expression Include

Question

Trans- acting regulators of gene expression include?
A) promoters
B) histone deacetylases
C) introns
D) silencers
E) the TATA box

Accepted Answer

Trans-acting regulators of gene expression are factors that can diffuse through the cytoplasm and act at target DNA sites. Histone deacetylases modify the chromatin structure, thereby regulating gene expression, and they act in a trans manner because they can affect any gene within the cell, not just the one they are associated with.
