Which of the following would allow gene expression to proceed?
A) X-chromosome inactivation
B) an increase in proteases
C) an increase in repressor proteins
D) a reduction in nucleases

Question

Quizplus · Accepted Answer

A reduction in nucleases would prevent the breakdown of mRNA, allowing it to be translated into protein, thus allowing gene expression to proceed. Option A (X-chromosome inactivation) describes a process related to dosage compensation in females, and is not directly related to gene expression in general. Options B (an increase in proteases) and C (an increase in repressor proteins) would actually decrease gene expression, by degrading proteins or preventing transcription, respectively.
