Over a longer period, what effect does insulin have on DNA and RNA to promote protein synthesis?
Explanation
Insulin's effects occur over different time scales. The most rapid effects involve membrane transport, followed by changes in enzyme activity. The slowest, most sustained effects involve changes at the genetic level, where insulin stimulates the transcription of genes coding for enzymes involved in energy storage.
