Here are four important roles of DNA:
1. **Genetic Information**: DNA carries the genetic information that determines an organism's traits and characteristics. It contains instructions for building and maintaining living organisms.
2. **Replication**: DNA can make copies of itself through a process called replication. This is crucial for passing genetic information from one generation to the next accurately.
3. **Protein Synthesis**: DNA provides the instructions for making proteins in a cell. Proteins are essential for various functions in the body, such as enzymes, hormones, and structural components.
4. **Inheritance**: DNA is passed from parents to offspring, allowing for the inheritance of genetic traits. This inheritance plays a vital role in the continuity of species and the diversity of life forms.
These are just a few of the key roles DNA plays in living organisms. Understanding these functions helps us appreciate the significance of DNA in the world of biology.
