Guanine is one of the four main nucleobases found in the nucleic acids DNA and RNA, the others being adenine, cytosine, and thymine (uracil in RNA). When mustard gas damages DNA by removing guanine or by other means, it can lead to mutations, which can cause serious deformities, particularly in developing embryos which are especially sensitive to genetic disruptions.
