During cell division, the genetic material condenses into discrete structures.

• A. Chromatin
• B. Chromosomes
• C. Genome
• D. Genes

Answer: (B)

During cell division, the genetic material condenses into discrete structures called chromosomes. In non-dividing cells, DNA exists as chromatin—loosely packed and accessible for transcription. As division begins, chromatin fibers coil tightly to form compact chromosomes, each typically consisting of two sister chromatids held at the centromere. This condensation makes the genetic material easy to separate and ensures accurate distribution to daughter cells. The genome refers to the entire set of genetic material, not a single condensed unit, and genes are specific sequences within DNA that code for traits, not the condensed structures themselves.
