Answer:
Nucleic acids.
Explanation:
Extremely helpful Bio mnemonics to remember are:
Carbohydrates & Lipids - CHO
Proteins - CHON
Nucleic acids - CHONP
Because of the "CHONP" mnemonic, I was immediately able to recognize the compound as a nucleic acid after seeing the "P", which represents phosphorous.
Carbohydrates, lipids, nor proteins will include "P"; only nucleic acids.
