Answer:

B

Explanation:

This macromolecule is DNA. Its stored genetic information in form of genes that translate to functional or structural proteins that make up an organism.  The DNA double helix is unzipped by helicases enzymes into single strands. RNA polymerase transcribes the single strands into mRNA. The mRNA is then translated into proteins by ribosomes. This is called the central dogma (DNA  RNA  Proteins).
