Webb29 aug. 2016 · Femtosecond spectroscopy has proved that thymine dimerization is an ultrafast photoreaction in which the CBDs are fully formed 1 ps after UV irradiation (272 nm) [ 9 ]. In contrast, cytosine (Cyt) CBDs are actual mutagenic hotspots, although the corresponding photoproducts (Cyt<>Cyt) are produced with relatively low yields. Webb9 dec. 2008 · The idea that the thymine dimer lesion is relatively non-disruptive to the overall DNA helix is supported by a variety of other mechanistic studies. The thermodynamic stability of duplexes containing a thymine dimer lesion have been studied by monitoring DNA melting by NMR and UV absorbance spectroscopy (9, 10, 13). Webb6 nov. 2009 · As a result of dimerization, the K D values were improved from 1.4 nM (V7t1) and 3.0 × 10 2 nM (del5-1) to 4.7 × 10 2 pM. The two aptamers were linked through ten thymine base units. It is possible that the affinity could be further improved by optimizing the length of the unit linking the two aptamers. tembang dolanan bahasa jawa
