B) It is DNA.
C) It is cylic AMP.
D) It is a polypeptide.
E) It is an inorganic compound.

Pyrimidines

Nitrogenous bases, each composed of a single ring of carbon and nitrogen atoms (e.g., thymine, cytosine, and uracil); components of nucleic acids. Compare with purines.

Phosphate Groups

Phosphate groups are chemical groups consisting of a phosphorus atom bonded to four oxygen atoms (PO4), important in energy transfer within cells.

Ribose Groups

Components of RNA molecules consisting of five-carbon sugars connected to the nucleobases and phosphate groups.
