| Description: |
The paper theoretically models the scattering spectra of ultrashort laser pulses on an RNA pseudonode and considers the possibility of using the obtained data in genome analysis. Several configurations of pseudo-RNA nodes were selected as a sample for theoretical modeling of the interaction of a laser pulse with matter: a hairpin, a double loop, and a spiral junction. The study of such structures is interesting for the analysis of the DNA genome, as well as for the study of functions such as viral replication, RNA splicing and RNA editing. At the moment, the study of such structural features is difficult, existing methods cannot give an accurate result, especially on long sections of the molecule. In this paper, the interaction of an ultrashort laser pulse with a molecule of four variants is theoretically modeled, when the RNA does not have a pseudonode and when there are hairpins and loops in the structure. The results obtained show the expediency of using laser pulses as a method for determining such structures.
В работе моделируются спектры рассеяния ультракоротких лазерных импульсов на псевдоузле РНК и рассматривается возможность использования полученных данных при анализе генома. В качестве образца для теоретического моделирования взаимодействия лазерного импульса с веществом было выбрано несколько конфигураций узлов РНК: шпилька, двойная петля и спиральное соединение. Полученные результаты показывают целесообразность использования лазерных импульсов в качестве метода определения таких структур. |
