Minor Components of the Dna of Physarum Polycephalum
DNA metabolism in the slime mold Physarum polycephalum was studied by centrifugation in CsCl of lysates of cultures labeled with radioactive thymidine at various times in the cell cycle. During the G(2) (premitotic) phase of the cell cycle, two components of the DNA are labeled. One component is lighter (buoyant density 1.686 g/cc) than the mean of the principal DNA (1.700 g/cc), and one is hea...
متن کاملLogical Modelling of Physarum Polycephalum
In the paper we proposed a novel model of unconventional computing where a structural part of computation is presented by dynamics of Plasmodium of Physarum polycephalum, a large single cell. We sketch a new logical approach combining conventional logic with process calculus to demonstrate how to employ formal methods in design of unconventional computing media presented by Physarum polycephalu...
متن کاملPhysarum polycephalum Histones
Physarumpolycephalum is an acellular slime mould whose histones are of general interest because they allow comparisons to be made between lower eukaryote and higher eukaryote histones and, perhaps more importantly, they provide a unique opportunity for the study of histone changes in the mitotic cycle, which is naturally synchronous in P. polycephalum plasmodia, and during differentiation. Stud...
متن کاملDNA methylation during differentiation of a lower eukaryote, Physarum polycephalum.
Starvation-induced differentiation of the slime mould Physarum polycephalum is accompanied by continuous methylation of DNA. No stable changes in the overall level of DNA methylation are evident, but a gene known to be transcribed specifically during differentiation is subject to increased methylation. Inhibitors of DNA methylation preclude differentiation of P. polycephalum, although they are ...
متن کاملPeriodic organisation of foldback sequences in Physarum polycephalum nuclear DNA.
Nuclear DNA from the slime mould Physarum polycephalum is shown to contain interspersed inverted repeat sequences, such that denatured fragments of DNA containing pairs of these sequences form intra-chain duplexes under appropriate conditions. The organisation and distribution of the nucleotide sequences responsible for the formation of foldback structures in Physarum DNA have been investigated...
