During interphase, DNA exists in a diffuse form known as what?

• A. Chromosome
• B. Chromatin
• C. Genome
• D. Nucleic acid

Answer: (B)

During interphase, DNA is not packed into visible chromosomes. It exists as chromatin, a diffuse complex of DNA wrapped around histone proteins. This looser organization keeps genes accessible for transcription and replication, allowing the cell to read and copy its genetic information. Only as the cell prepares to divide does chromatin condense into the dense chromosomes seen under the microscope. The other terms refer to broader ideas (the whole set of genetic material or the chemical nature of DNA/RNA) rather than the organized state of DNA in the nucleus during interphase.
