Question

What biomolecules contain nitrogen? Select all that apply.


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
