Question

Quizplus · Accepted Answer

Genetic switches are regulatory elements that control the use of the genetic toolkit and when and where genes are turned on. This is achieved through a process called transcriptional regulation, where the switch controls the activity of RNA polymerase in transcribing specific genes. Therefore, both A and B are correct. However, genetic switches do not involve translational activation, which eliminates option C. They also do not counteract modularity in development, making option D incorrect.
