You wish to learn if the initiation of root hair formation depends on either translation or transcription. Roots were treated with actinomycin D, cycloheximide, and mock treated with a control solution without either of the two inhibitors. You find that root hair initiation was inhibited when mock treated with the control solution and in the presence of either cycloheximide or actinmycin D. From this you can conclude that:
A) Both transcription and translation are required. B) Only transcription is required. C) Only translation is required. D) More data is needed.
