A useful attribute of immediate early genes for neuron visualization techniques is that
A) immediate early genes fluoresce when active.
B) these genes quickly reduce their activity level.
C) immediate early genes control glucose utilization.
D) the presence of the gene product in the nucleus is a marker of neuron activation.
E) immediate early gene activation can be detected by CT scans.

Question

Quizplus · Accepted Answer

Immediate early genes encode for transcription factors that are rapidly induced upon neuronal activation. Once activated, these transcription factors bind to DNA and regulate other genes responsible for various cellular functions, including the production of proteins that allow the visualization of active neurons. Therefore, the presence of the immediate early gene product in the nucleus serves as a marker of neuron activation, which can be used in visualization techniques such as immunohistochemistry or in situ hybridization.
