Answer» Correct OPTION is (C) No part of it TRANSCRIBED Explanation: DNase would only get access to uncondensed DNA. Uncondensed DNA is transcriptionally active. As the DNase would have cleaved the fully or partially transcriptionally active DNA, and our fragment is intact, we can SAY it was not at all being transcribed.
