Спектральнi властивостi фрагментiв теломери
The optical absorption and phosphorescence (at low temperatures) of a telomere fragment (oligonucleotide d(AGGGTTAGGGTTAGGGTTAGGG)) and (for comparing) the DNA macromolecule are investigated under various excitation wavelengths (240–300 nm). Two types of d(AGGGTTAGGGTTAGGGTTAGGG) samples were studie...

M. optical absorption phosphorescence adenine chromophore thymine chromophore oligonucleotide d(AGGGTTAGGGTTAGGGTTAGGG) - The optical absorption and phosphorescence (at low temperatures) of a telomere fragment (oligonucleotide d(AGGGTTAGGGTTAGGGTTAGGG)) and (for comparing) the DNA macromolecule are investigated under various excitation wavelengths (240–300 nm). Two types of d(AGGGTTAGGGTTAGGGTTAGGG) samples were studied: (1) the intact sample, and (2) the sample heated to 90 ∘C and studied immediately after heating. It is concluded that the main traps of triplet electronic excitations in both these samples of d(AGGGTTAGGGTTAGGGTTAGGG), as well as DNA, are the complexes formed by neighbor adenine (A) and thymine (T) chromophores from the same strand (not from complementary chromophores of the different strands). У роботi наведенi результати дослiджень спектрiв оптичного поглинання та фосфоресценцiї (при низьких температурах) фрагмента теломери – олiгонуклеотида д(AГГГTTAГГГTTAГГГTTAГГГ) та (для порiвняння) макромолекули ДНК при рiзних довжинах хвиль збуджуючого свiтла (240–300 нм). Дослiджено два типи зразкiв д(AГГГTTAГГГTTAГГГTTAГГГ): (1) неушкоджений зразок та (2) зразок, нагрiтий до 90 ∘C. Зроблено висновок про те, що пасткою триплетних електронних збуджень в олiгонуклеотидi д(AГГГTTAГГГTTAГГГTTAГГГ), так само як i в ДНК, є комплекс, сформований мiж сусiднiми аденiновою (А) та тимiновою (Т) хромофорами з одного i того самого ланцюга (але не мiж вiдповiдними комплементарними хромофорами рiзних ланцюгiв).
