Which term describes the long DNA-protein complex found in the nucleus during interphase?

• A. Chromatin
• B. Chromosome
• C. Pedigree chart
• D. Meiosis

Answer: (A)

During interphase, genetic material exists as chromatin, a long DNA-protein complex inside the nucleus. Chromatin is made of DNA wrapped around histone proteins, forming a loose, thread-like network that allows genes to be expressed and copied. When a cell prepares to divide, chromatin condenses into visible chromosomes. The other terms describe something else—chromosome is the condensed form seen during mitosis, a pedigree chart is a family inheritance diagram, and meiosis is a type of cell division that creates gametes. So the long DNA-protein complex present in the nucleus during interphase is chromatin.
