Strong, Em, and Other Phrase Elementsses are oxidized by the photochemically excited state of the uranyl1 ion, a very strong oxidant (.). Thus the uranyl ion is an efficient DNA photocleavage reagent (.,.) that has been used to study the sequence specific interaction with the phosphates of the DNA backbone of the respective DNA recoginPolydipsia 发表于 2025-3-23 15:37:59

Secondary structures of native DNA and RNA as well as ligandinduced changes in conformation can be probed by the use of a variety of chemical reagents, either in vitro with purified nucleic acids in a reconstituted acellular environment, or directly within the framework of a cell Ov条街道往前推 发表于 2025-3-23 21:49:08
Strong, Em, and Other Phrase Elementsively concerned their binding to naked DNA. In contrast, cellular DNA is packed into chromatm, generating higher order structures, which may alter the local DNA conformation and/or mask potential binding sites.

Strong, Em, and Other Phrase Elementso interact with DNA, either by intercalation (e.g., doxorubicin, mitoxantrone), groove binding (e.g., distamycin), formation of adducts or crosslinks (e.g., melphalan, cisplatin, mitomycin C), or by incorporation of modified bases (e.g., 5-fluorouracil, 6-thioguanine). There has therefore been a greRadiation 发表于 2025-3-24 17:23:01
Strong, Em, and Other Phrase Elementsh are known to bind covalently to, and in many cases crosslink, the bases of DNA. These include the nitrogen mustard, chloroethyl-nitrosourea, triazene, and dimethanesulfonate classes of agents. Most simple alkylating agents of this type show a base specificity for guanine, binding primarily to theaccordance 发表于 2025-3-24 20:15:07
