dif site prior to cell divison. XerC/XerD recombination is an example of site-specific recombination found in almost all bacteria. Three critical factors are involved in this recombination reaction: the DNA translocase FtsK‚ tyrosine recombinases XerC/XerD and the specific site dif. The chromosome dimer resolution is done after the activation of XerD by the γ sub-domain of FtsK at the dif site. When stimulated by FtsK‚ XerD exchanges the first pair of strands to form a Holliday junction which is then

In an isotonic environment‚ the amount of water and solute are the same both inside and outside of the cell. As water drifts into the a cell‚ the same amount flows out creating a balanced environment both inside and outside of the cell. When there is a high level of
