Long-lived fluorescence of homopolymeric guanine-cytosine DNA duplexes.
The fluorescence spectrum of the homopolymeric double helix poly(dG) x poly(dC) is dominated by emission decaying on the nanosecond time-scale, as previously reported for the alternating homologue poly(dGdC) x poly(dGdC). Thus, energy trapping over long periods of time is a common feature of GC duplexes which contrast with AT duplexes. The impact of such behaviour on DNA photodamage needs to be...
متن کاملFluorescence of DNA Duplexes: From Model Helices to Natural DNA
Recent fluorescence studies of DNA duplexes with simple repetitive base sequence have revealed important collective effects which are very sensitive to conformational disorder. In contrast to the monomeric chromophores, whose fluorescence lifetimes are shorter than 1 ps, the fluorescence decays of duplexes span several decades of time. The occurrence of excitation energy transfer, evidenced by ...
متن کاملFluorescence probing of aminofluorene-induced conformational heterogeneity in DNA duplexes.
Fluorescence spectroscopy was used to study carcinogen-induced conformational heterogeneity in DNA duplexes. The fluorophore 2-aminopurine (AP) was incorporated adjacent (5') to the lesion (G*) in eight different DNA duplexes [d(5'-CTTCT PG* NCCTC-3'):d(5'-GAGGN XTAGAAG-3'), G* = FAF adduct, P = AP, N = G, A, C, T, and X = C, A] modified by FAF [ N-(2'-deoxyguanosin-8-yl)-7-fluoro-2-aminofluore...
متن کاملFolding RNA/DNA hybrid duplexes
MOTIVATION While there are numerous programs that can predict RNA or DNA secondary structures, a program that predicts RNA/DNA hetero-dimers is still missing. The lack of easy to use tools for predicting their structure may be in part responsible for the small number of reports of biologically relevant RNA/DNA hetero-dimers. RESULTS We present here an extension to the widely used ViennaRNA Pa...
متن کاملDistinct frequency-distributions of homopolymeric DNA tracts in different genomes.
The unusual base composition of the genome of the human malaria parasite Plasmodium falciparum prompted us to systematically investigate the occurrence of homopolymeric DNA tracts in the P. falciparum genome and, for comparison, in the genomes of Homo sapiens , Saccharomyces cerevisiae , Caenorhabditis elegans , Arabidopsis thaliana , Escherichia coli and Mycobacterium tuberculosis. Comparison ...
