DNA acting like RNA.
Over the last decade or so, secondary non-B-DNA structures such as G-quadruplexes and i-motifs have come into focus as biologically functioning moieties that are potentially involved in telomeric interactions and the control of gene expression. In the present short review, we first describe the structural and dynamic parallels with complex RNA structures, including the importance of sequence an...
متن کاملActing like Actin
The crawling movement of eukaryotic cells requires establishment of cell polarity, extension of the leading edge, attachment to the substratum, and retraction of the cell body. Each of these events depends on the dynamics of the actin cytoskeleton that are orchestrated by a host of signaling molecules and actin-binding proteins. Indeed, amoeboid cell motility involves so many biochemical compon...
متن کاملThe Turnover of Nuclear Dna-like Rna in Hela Cells
The subcellular distribution of various types of RNA in HeLa cells is described. In addition, the relative rate of synthesis of the major classes of nuclear RNA has been determined. From these experiments it can be deduced that the heterogeneous nuclear RNA fraction is rapidly synthesized and degraded within the cell nucleus.
متن کاملCis-acting influences on Alu RNA levels.
The human short interspersed repeated element (SINE), Alu, amplifies through a poorly understood RNA-mediated mechanism, termed retroposition. There are over one million copies of Alu per haploid human genome. The copies show some internal variations in sequence and are very heterogeneous in chromosomal environment. However, very few Alu elements actively amplify. The amplification rate has dec...
متن کامل3 Acting Like an Individual versus Feeling Like an Individual
ion. (p. 51) With this statement, Turner et al. (1987) were distancing themselves from the group mind idea, originally put forward by Le Bon (1896) and McDougall (1921) at the turn of the twentieth century to explain crowd behavior. Turner et al. took pains, in their original theory and elsewhere, to explain that depersonalization is not like a group mind, not an altered state of consciousness,...
