Pelagic-benthic coupling and diagenesis of nucleic acids in a deep-sea continental margin and an open-slope system of the eastern Mediterranean

Article Abstract:

The nucleic acid fluxes, sedimentary DNA and RNA concentrations and the enzymetic hydrolyzable fraction of DNA in the bathyl continental margin and an open sea system of the Eastern Mediterranean were compared and studied. The results revealed that the preservation of DNA in deeper sediments layers favored in benthic system characterized by high sedimentation rates.

Extracellular nucleic acids

Article Abstract:

The study observation of early tumor diagnotics based on analysis of circulating DNA and RNA which indicate the possibility of nucleic acid exchange between eukaryotic cells and extracellular space suggesting their participation in unidentified biological processes is reported.
