Abstract. The conformational features of the intercalation site in polynucleotides were examined. We found that, for all the crystal structures of drug-dinucleoside complexes studied thus far, two torsion angles differ from those found in A RNA (phi and chi) and that alternate sugar puckering is not a prerequisite for by: One important mechanism in the interaction of carcinogens with DNA is base intercalation. This phenomenon is common with polycyclic aromatic structures, e.g., polycyclic aromatic hydrocarbons and aflatoxin B process involves “stacking” of an aromatic ring(s) between two bases, particularly purines.
The strongest complex is computed, however, for the mixed hexanucleotide d (CGTACG)2, containing the intercalation site between two CG base pairs and an adjacent TA base pair. The overall sequence preference is the result of an intricate interplay of sequence preferences of the constituents in particular of daunosamine and the 9-OH by: Binding of polycyclic aromatic hydrocarbons to polyadenylic acid.

INTERCALATION OF HYDROCARBONS IN POLYNUCLEOTIDES INTRODUCTION A number of laboratories have established that a group of polycyclic, aromatic hydrocarbons will complex to DNA (2,5,6,7,13,20,24,25,28,30, 31,34,36). Polycyclic, aromatic hydrocarbons are practically insoluble in water; however, their solubility is greatly enhanced in DNA solutions.
The flow dichroism of four poly A-hydrocarbon complexes was measured. The flow dichroism measurements were consistent with the intercalation model. The dissociation energy of several hydrocarbons is found to occur in an order that is different from that given by the size : Albert Morrie Craig.
Graduation date: The binding of eleven polycyclic, aromatic hydrocarbons to the acid\ud form of poly A has been investigated. Intercalation on hydrocarbons in polynucleotides book hydrocarbons were chosen to\ud test a size criterion.

Real-World Reading Link If you have ridden in a car or a bus, you have used. Intercalation Compounds. Graphite intercalation compounds (GIC) are composed of planes of intercalant atoms or small molecules separated by a few graphitic sheets, in a sequence that repeats periodically along the c-axis as in a superlattice.
The number of graphitic layers stacked between two successive intercalant planes is called the stage of the GIC.

Thus, you can well understand the importance of hydrocarbons in your daily life. In this unit, you will learn more about hydrocarbons. CLASSIFICATION Hydrocarbons are of different types. Depending upon theFile Size: 1MB. This book discusses several topics, including DNA replication, calculation of intermolecular energies, and thermodynamic parameters of polynucleotides.
Organized into 35 chapters, this book starts with an overview of the specific association of the purine and pyrimidine bases in the nucleic acids, which provides the basis for storage Book Edition: 1. Polycyclic aromatic hydrocarbons (PAHs) are aromatic hydrocarbons with two or more fused ben- zene rings in various structural configurations (Blumer, Blumer et al.Vichi, Pizzale et al.Haritash and KaushikKim, Jahan et al.Jiang, Yang et al.

This results in a more or less pronounced expansion which may be detected by X-ray diffraction and which occurs in a direction perpendicular to the carbon sheets. We previously published comprehensive linear and circular dichroism studies of MB interactions with DNA and polynucleotides, which demonstrated intercalation of MB with most duplex DNA sequences as well as triplex poly(dT) ⁎ poly(dA)poly(dT).Cited by: 3.
