What carries thousands of genes and is located in the nucleus of every human cell?

• A. DNA
• B. Nucleus
• C. Chromosomes
• D. Genes

Answer: (C)

Genetic material is organized into chromosomes inside the nucleus. A chromosome is a long DNA molecule wrapped around proteins and packaged into a distinct structure that carries many genes along its length. Because there are thousands of genes distributed across the chromosomes, each chromosome carries a large number of genes, and together the set within the nucleus holds the whole genome. While DNA is the material that stores genetic information and the nucleus is where it resides, the description points to chromosomes as the carriers of thousands of genes in the cell.
