Chromosome replication in Escherichia coli. IV. Control of chromosome replication and cell division by an integrated episome.
TLDR
It is concluded that, in the Hfr temperature resistant strains, chromosome replication and cell division are under F control, and in these cells the chromosome has become part of the F replicon. Expand
A cold sensitive dnaA mutant of E. coli which overinitiates chromosome replication at low temperature
TLDR
A heat resistant mutant of E. coli dnaAts46 was isolated, which grows normally only at temperatures above 39° and overproduces DNA relative to protein after a temperature shift from 42° to 32° due to overinitiation of rounds of chromosome replication at low temperature. Expand

TLDR
Electron microscopic radioautographs of guinea pig pancreatic exocrine cells demonstrated that, at the time studied, newly synthesized proteins were concentrated in the structures of the Golgi complex and especially in large vacuoles partially filled with a dense material. Expand
Origin and sequence of chromosome replication in Escherichia coli.
Two methods have been used to determine the origin and direction of chromosome replication in Escherichia coli: gradient of marker frequency and sequence of replication in synchronized cultures. InExpand
Expression of F transfer functions depends on the Escherichia coli integration host factor
TLDR
Evidence is presented that the Escherichia coli DNA binding protein, IHF, plays an important role in conjugal transfer of the plasmid F. coli by positively effecting transcription of the transfer (tra) operon of theplasmid. Expand
Isolation of Hfr Strains from R+ and ColV2+ Strains of Escherichia coli and Derivation of an R′lac Factor by Transduction
TLDR
Temperature-resistant revertants were isolated from Escherichia coli strains carrying a temperature-sensitive dnaA mutation and either a repressed or a derepressed F-like R factor or a ColV2 factor, offering a good selection for Hfr strains produced by integration of various episomes and for the isolation of R' factors. Expand
Replication of the prophage P1 during the cell cycle of Escherichia coli
TLDR
The variation in the number of copies of prophage P1 relative to two chromosomal markers when the doubling time of the host cells is modified by a change in carbon source suggests that P1 retains the ability to replicate after chromosome initiation has stopped and in the absence of essential amino acids. Expand
THE MOLECULAR WEIGHT OF LAMBDA DNA.

  • 1 February 1965
TLDR
It seemed that DNA dried in vacuum after being attached to a film of protein retained the B configuration, and actinomycin was found to increase enormously the sensitivity to shear of λ DNA. Expand
The nucleotide sequence of replication and maintenance functions encoded by plasmid pSC101.
TLDR
The nucleotide sequence of 1100bp around the origin of replication of the pSC101 plasmid has been determined and includes the sequence of the par region involved in partitioning of plasmids at cell division. Expand
