Question

What compound is this?
Carbohydrates
Lipids
Nucleic acids
Proteins ​​​

Answer 1

Nucleic acids.

Step-by-step 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.
