Investigation of G-Quadruplex DNA cleavage through development of a solution-based fluorescent assay
MetadataShow full item record
In vitro, G-rich sequences form highly stable secondary structures known as G-Quadruplexes. These structures have been characterized by circular dichroism nuclear magnetic resonance and X-ray crystallography; although their detection in vivo has remained elusive. Due to the biological implication of a transisent and polymorphic secondary structure forming within the hypothetical G-Quadruplex forming regions, there is growing interest to understand their in vivo molecular dynamics.
