32. Safe use: not produce any organic chloride and other harmful substances that may lead to carcinogenesis, teratogenesis and mutagenesis, such as THMS and chloroform.

33. Using ENU mutagenesis we have identified a mouse model resembling human maple syrup urine disease.

34. Cell cycle analysis can provide reference for researching the physical and chemical mutagenesis to citrus calli.

35. This paper includes enzyme crosslinking, site - directed mutagenesis, small molecular compounds, homo - functionality polymerization, cofactor introduction.
