A student claims that transcription factors, regulators, and activators only allow eukaryotic cells to turn on genes when they are needed, but do not help to shut down genes when the genes are not needed. Evaluate the accuracy of the student's statement. The statement is incorrect because transcription factors, regulators, and activators help shut down gene expression by their absence. The statement is incorrect because activators allow eukaryotic cells to turn on genes when they are needed, and transcription factors and regulators function to shut down genes when the genes are not needed. The statement is incorrect because some transcription factors, regulators, and activators can shut down some genes by binding to sites on DNA. The statement is accurate as written.
