Option A is partially correct as DNA is completely replicated during the S-phase of the cell cycle, but only a small portion of the DNA is transcribed into RNA. Option B is completely wrong as DNA must be completely replicated before any transcription can take place. Option C is also correct as transcription is regulated and can be activated or repressed in different cell types or at different stages of development. Therefore, the best option is D, which correctly states that DNA is completely replicated but only partially transcribed and that transcription can be activated at different times in different cells of the body.
