blueprint of life

The blueprint of life refers to DNA, the molecule that contains the instructions for building and functioning living organisms. Think of it like a detailed manual written in a code, which determines traits like eye color, height, and how cells grow. DNA is made up of sequences of chemical bases, which encode information much like letters in a sentence. This code is copied and read by cells to produce proteins, the workhorses that carry out biological functions. Essentially, DNA provides the fundamental plan that guides how life develops, operates, and adapts.
