> ### Creating a Molecular Object

> In the beginning, we have to create a molecular scene.
> We build a polypeptide from an amino acid sequence, a so-called molecular object,
> by opening the PeptideBuilder dialog via the menu entry
> "Build->BuildPeptide".
> Then enter the sequence "ARND" in the label field at the top.
> (As an alternative, you can also press the upper four amino acid buttons.)
> This will create a polypeptide with the amino acid sequence
> Alanin, Arginin, Asparagine, Aspartic acid.
> Then press the "Build" button.
> Press Next to continue.
