Final stages of cytokinesis in amoeba: Does biology lose control?

We discuss some basic scaling laws in the the final stage of cell division of Dictyostelium discoidium and Entamoeba Invadens, describing the action of motors during cytokinesis. Various regimes are presented, and the effects of mutation and defects are surveyed. The appearance of collective behavior as a remedy for defective division is demonstrated.

 

News
  • Coming Soon... Dave Boal's new book on Biophysics...theatres, oops, bookstores near you. Will post the details later.
  • Check out this article "DNA-Inspired Electrostatics" in Physics Today September, 2000 issue. The article is very well written, and it cites one of our people Dr.Bae-Yeun Ha's work as a major contribution to this field. The topic itself is very interesting as well.
  • Barbara Frisken is on sabbatical at Harvard starting this Fall (2000).
