• transposition
  • P element transposition is related to retroviral DNA integration, such as HIV, and to the process by which immunoglobulin and T-cell receptor genes are rearranged in the vertebrate immune system [V(D)J recombination]. (berkeley.edu)
  • Current studies involve the use of imaging methods, including atomic force microscopy (AFM), electron microscopy (EM) and total internal reflection fluorescence microscopy (TIRFM) to understand the role(s) that GTP plays in transposition, the detailed reaction pathway and how this cofactor modulates the assembly and activity of transposase on DNA. (berkeley.edu)
  • A second mechanism for inducing genomic rearrangements is alternative transposition of class II elements in bacteria, plants, and animals. (asmscience.org)
  • Some features of both transposable elements and hosts suggest coadaptations to mitigate the reduction of fitness expected from unfettered transposition, and to provide a wide range of new variations on which natural selection can act. (asmscience.org)
