Question

Nuclear DNA exists as complex of nucleoprotein called __A__ that condenses into__B__ during __C__. These A, B, C are respectively

• A. Chromatids, Chromosomes, Interkinesis.
• B. Chromosomes, Chromatin, S-phase.
• C. Chromatin, Chromosome, Interphase.
• D. Chromatin, Chromosome, M-phase.
