Topic Reactions in major groove of DNA

DNA bearing reactive functional groups in major groove will be prepared by polymerase incorporations of modified nucleoside triphosphates. Bioorthogonal reactions of these groups will be studied, e.g. cross-linking with proteins or reactions changing the size and bulkiness of the substituents for switching or triggering of interactions of DNA with proteins.
