- The hereditary information is stored in the DNA, which is organized into chromosomes within the nucleus of a cell.
- Genes are specific sequences of DNA that code for specific proteins or traits. Each gene contains the instructions for making a particular protein or determining a specific characteristic of an organism.
- Chromosomes are long strands of DNA that are tightly coiled and contain many genes. They serve as the physical structure that organizes and carries the genetic information in the cell.
