Gene expression is often assayed by measuring the level of mRNA produced from a gene.If one is interested in knowing the amount of a final active gene product,a potential problem of this method is that it ignores the possibility of _____.
A)chromatin condensation control
B)transcriptional control
C)alternative splicing
D)translational control

Question

Quizplus · Accepted Answer

Translational control can regulate the amount of active gene product, as it involves regulating the translation of mRNA into protein. This can be achieved through factors such as RNA-binding proteins and microRNAs that can inhibit or enhance translation. Therefore, measuring mRNA levels alone may not accurately reflect the amount of active gene product present. Options A, B, and C refer to various forms of transcriptional regulation that can affect the production of mRNA, but do not directly address the issue of translational regulation.
