What is DNA? What is its purpose?

The molecule of information is DNA. It holds the blueprints needed to create proteins, which are other big molecules. Each of your cells has these instructions, which are dispersed throughout 46 lengthy structures known as chromosomes. Numerous smaller DNA fragments known as genes make up each of these chromosomes.
