E. coli competence

[Abramo C Ottolenghi]

The drop between the two peaks can be explained physiologically.  If as I 
suspect the cells are in "near" synchrony, there might be a point inthe cell 
cycle at which they might be more amenable to becoming competent.  There is 
evidence that the phospholipids of the membrane change when  it has to
curve for septation. (several papers by Vic Norris of the University of
Leicester.
