Optical studies of DNA-wrapped carbon nanotubes
… of phonon-assisted relaxation processes in DNA-wrapped single walled carbon nanotubes. Using resonance Raman spectroscopy (RRS) and photoluminescence spectroscopy (PL), a careful characterization has been carried out on different DNA-wrapped SWNT samples to study the effects of DNA wrapping …

Centromere Identity and the Nature of the Cenp-A-Containing Nucleosome
… While most centromeres form on repetitive DNA, the underlying DNA sequence is neither necessary nor sufficient to support centromere function, suggesting that this locus is epigenetically defined. The histone H3 variant centromere protein A (CENP-A) replaces H3 in nucleosomes at the …

Length dependence of the Raman spectra of carbon nanotubes
DNA-wrapping technology, combined with size-exclusion chromatography, have made possible the sorting of carbon nanotubes according to length. In particular, length sorted nanotube samples, with finite lengths approaching the exciton size, are now available. Hence, experiments that explore the …

Discovery of a Novel Metalloregular Family: Structure/Function Studies of E. Coli Rcnr
… factors, RcnR/CsoR proteins contain a unique DNA binding motif that recognizes DNA sequences containing G-tracts flanked by AT-rich inverted repeats. RcnR binds to a pair of sites in the rcnA-rcnR intergenic region leading to DNA wrapping, and repression of both genes. The identification of …

Deriving Structural Insights About Mesoscale Chromatin Folding Using Coarse-Grained Oligonucleosome Modeling
… drives the shape of the distribution of DNA fragment lengths resulting from ionizing-radiation damage. Pair-wise DNA-DNA contact data from DNA sequencing-based assays have the potential to provide locus-specific information about the relationships between chromatin structure and function. …
