Dna contains instructions for making the different molecules that a cell needs to grow and function. for example, is made by

a- a protein, translating mrna
b- mrna, translating dna c- a protein, transcribing mrna
d- mrna, transcribing proteins

Proteins are made by the translation of mRNA (via tRNA molecules.) This process is essential for everyday life because proteins perform necessary functions. The protein is your end goal, even though to get there you have to first transcribe DNA to mRNA, then translate mRNA.
