What is DNA and how does it determine our traits?

DNA, or deoxyribonucleic acid, is a molecule that carries the genetic instructions for the development, functioning, growth, and reproduction of all known organisms. These genetic instructions are determined by the sequence of the four DNA bases: adenine (A), thymine (T), cytosine (C), and guanine (G). The sequence of these bases forms genes, which determine specific traits. For example, the genes responsible for eye color or height are determined by the specific sequences within the DNA. Understanding the role of DNA and genes is crucial in understanding how our traits are inherited and passed down from one generation to the next.
