Water is the clear, colorless, odorless, tasteless liquid each molecule of which contains one atom of oxygen and two atoms of hydrogen (H2O). MNNG is a guanidine derivative with a nitro group (-NO2) on the nitrogen at position 3 and a methyl group (-CH3) and nitroso group (-NO) on the nitrogen at position 1. MNNG acts by adding alkyl groups to the O6 of guanine and O4 of thymine of DNA, giving it potent mutagenic and carcinogenic properties.
