Comparisons of the sequences of several bacterial sigma factors suggested conserved regions in E. coli s70  that interact directly with promoters DNA-binding regions of the sigma factor fold into independent domains in the protein regions 1.2, 2.3– 2.4, 3.0, and 4.1–4.2.

In E. coli, two clusters of five ter sites each, including terK, -I, -E, -D, and -A on one side and terC, -B, -F, -G, and -H on the other, are located 100 kb on either side of this termination region.

Each set of ter sites is specific for one direction of fork movement

For isopycnic separation , density centrifugation is continued until the buoyant density
of the particle of interest and the density of the gradient are equal.
