A scientific debate: The sword that cleaves chaos of DNAzyme catalysis research

Therapeutic DNAzymes with RNA depleting effect are multifunctional building blocks for constructing biological materials. In a recent work published in Nature Chemistry, Holliger group and Chaput group had a wonderful debate base on previously reported approach for tailoring DNAzymes with high mRNA cleavage activity in mammalian cells. Their perspective pushes the catalytic mechanism investigation of DNAzymes to a new stage with more standardization and clarity.
