Why is DNA called the blueprint of life?

DNA regulates the synthesis of proteins, which carry out the majority of cellular functions and serve as the fundamental building blocks of structure and function in organisms' cells. This is why DNA is referred to as the blueprint of life; it contains the instructions required for an organism to grow, develop, survive, and reproduce.

DNA is an informational code that controls how cells and organisms develop and function. Genes are segments of DNA that code for the production of particular proteins. The intricate information in DNA controls which proteins are made when and in what amounts. A person's genetic makeup is largely determined by their DNA.

A blue print is an informational map that guides the construction of a building. It outlines the materials that must be used when and in what quantities during the building process. It is possible to predict the building's final design by examining a blue print.

Although the analogy is a little off, it gives an idea of what DNA does.

DNA is called the blueprint of life because it contains the instructions needed for an organism's growth, development, functioning, and reproduction. It carries the genetic information that determines an organism's traits and characteristics.
