Is dna organized into chromosomes
WebThe DNA inside the nucleus is organized into chromosomes. At the most basic level, a chromosome is a molecule of DNA that is tightly coiled around proteins called histones. Eukaryotic cells have multiple chromosomes that are linear in shape. 2. Each chromosome contains a molecule of DNA that is wound tightly around clusters of histone proteins. WebDuring some stages of the cell cycle, the long strands of DNA are condensed into compact chromosomes. Eukaryotes, whose chromosomes each consist of a linear DNA molecule, employ a complex type of packing …
