Chromosome-Chromatin-Nucleosome? A. Histone proteins condense DNA. DNA first wraps around histone proteins, then are coiled into a nucleosome B. Condensed DNA is difficult to express so interphase DNA is condensed rarely. Note: normal expression-DNA makes RNA makes protein, so difficult to express means DNA stays "still" and no RNA or protein produced. C. Condensed DNA allows easier access to transcription enzymes like transcription factors and RNA polymerase. D. A and B are correct E. A and C are correct
