WebIn Escherichia coli, it is estimated that about 15% of the cells in a standard laboratory culture require Xer activity to produce viable progeny. In cells carrying unresolved dimers (i.e., mutated for Xer), division proceeds and traps DNA, bisecting the dimeric chromosome. WebDec 12, 2000 · Titration of chromosome superhelicity in E. coli strains deficient in MukB or SeqA. Escherichia coli chromosomes are folded into nucleoids, which are nucleoprotein complexes packaged into 50–100 negatively supercoiled domains. Binding of an intercalative drug such as ethidium bromide leads to reduced negative superhelicity. deutsche dance charts top 100

One outcome is that one of two semi-conservatively replicated F plasmids remains in the donor cell and another is now in the recipient cell. In this case, the recipient cell becomes a new F+ donor cell! 2. The other outcome is integration of the F plasmid into recipient cell chromosomal DNA.
