To build a polymer, drag the monomer subunits from the toolbox to the workspace. Use the water molecule to break the bond between the last two subunits.

Combine the different sugar monomers to see what subunits form sucrose, maltose, and lactose. To add subunits, drag and drop them from the toolbox to the workspace.

Fats are made of glycerol and fatty acid molecules. Combine the right mixture of these two molecules to make a fat molecule known as a triglyceride. To add subunits, drag and drop them from the toolbox to the workspace.

Make a polypeptide by dragging and dropping amino acid subunits from the toolbox to the workspace. These chains are made at the ribosome during translation. To view a polypeptide folding into a protein, click on the Protein Structure tab.

Toggle between the DNA and RNA buttons to piece together strands of the two different nucleic acids. To add subunits, drag and drop them from the toolbox to the workspace.
