Why is the dna molecule referred to as the "blueprint of life"

All life has DNA Also DNA basically depends how you turn out like. Personality, Hair color, Eyes, Etc. I hope i helped :D

Yes DNA is responsible for your genes but its biggest job is basically a blueprint/code for creating proteins that are necessary throughout your whole body. the DNA unzips , mRNA copies half of the DNA, mRNA goes to the ribosome, the tRNA brings the amino acids, the rRNA builds up the protein, goes to the endoplasmic reticulum, then to the golgi apparatus, which then is packaged into a vacuole and sent throughout your body to bring it the proteins it needs .
