What biomolecules contain nitrogen? Select all that apply.

Question

Proteins

Lipids

Carbohydrates

Nucleic acids

Answer 1

The biomolecules that contain nitrogen are:

• Proteins: They are made up of amino acids, which contain nitrogen in their amino group (–NH2).
• Nucleic acids: DNA and RNA contain nitrogenous bases (adenine, thymine, cytosine, guanine, and uracil in RNA) that include nitrogen.

Lipids and carbohydrates do not typically contain nitrogen in their structure.

So, the correct choices are:

• Proteins
• Nucleic acids
