It is mandatory for RNA, and Peptide, but not for CHEM.
Difficult to find a better alternative solution since it is only mandatory in some circumstances. Close.
My mistake - it is mandatory, so a star needs to be in place.
Star now present. Close.
In the monomer page, when adding a new RNA monomer, the natural analogue is mandatory but there is no red star next to title.
