Question

Quizplus · Accepted Answer

Events that occur inside of the cell, such as signaling pathways, can excite or inhibit genetic expression. This is why certain genes may only be turned on in certain cell types or under certain circumstances. Option A is incorrect because genes can actually work collaboratively to produce a particular trait or protein. Option B is incorrect because some genes code for multiple proteins through alternative splicing. Option C is incorrect because environmental factors, such as nutrition and stress, can impact genetic expression.
