Popis | Cytosine-rich oligodeoxynucleotides (C-rich ODNs) play diverse roles in the regulation of protein expression at both transcriptional and translational levels. A repetitive C sequence can be responsible for some diseases. It is commonly known that C-rich ODNs form the stable i-motif structure, interesting due to a crucial role in the process of genetic information transfer. The aim of this contribution is to find out the relationship between the structure of homo-ODNs in buffered solutions with the same ionic strength (I = 0.18 M) but with a different number of cytosines (dCx; x = 3, 4, 5, 6, 9). Using linear sweep voltammetry (LSV) and elimination voltammetry with linear scan (EVLS), electrochemical reduction signals studied on a mercury electrode reflect the conformation changes of the C-rich ODN chain. |
