Predictor of Natural Disordered Regions or PONDR is one of the best available algorithms for predicting the likelihood that a given amino acid residue is in a region of intrinsic disorder, based on the surrounding amino acid sequence and amino acid composition.

The replication cycle can be defined in terms of two constants: C and D

C is the fixed time of 40 minutes required to replicate the entire E.coli chromosome. Its duration corresponds to a rate of replication fork movement of 50,000 bp/minute.

D is the fixed time of 20 minutes that elapses between the completion of a round of replication and the cell division with which it is connected. This period may represent the time required to assemblethe components needed for division.

Upwelling zones (where nutrients reach the surface from deeper waters) and continental shelf areas (where bottom sediments in shallow water rapidly exchange nutrients with surface waters) support greater production.

Freshwater production is highest in rivers, shallow lakes, and ponds, where nutrients are most abundant, and lowest in clear streams and deep lakes.
