TLDR
The bacterial chromosome, while evolving by point mutations in its DNA, is thought to be rather stable with regard to its gross organization.Abstract:
The bacterial chromosome, while evolving by point mutations in its DNA, is thought to be rather stable with regard to its gross organization. For example, even though the DNAs of Salmonella and Escherichia cross-hybridize only weakly due to divergent sequence evolution (Demerec and New, 1965; Brenner et al., 1969), the genetic maps of the two bacteria are rather similar with respect to the order of functions (Sanderson and Demerec, 1965).read more

Positive selection procedure for entrapment of insertion sequence elements in gram-negative bacteria.
TL;DR: The broad-host-range plasmid pUCD800 containing the sacB gene of Bacillus subtilis for use in the positive selection and isolation of insertion sequence (IS) elements in gram-negative bacteria was constructed in this article.

Sequences of mouse immunoglobulin light chain genes before and after somatic changes
TL;DR: The nucleotide sequences of the germ line gene as well as a corresponding somatically mutated and rearranged gene coding for a mouse immunoglobulin lambdaI type light chain are determined and confirm the previously drawn conclusion that an active complete lambdaI gene arises by somatic recombination.

Antibiotic Activity of Xenorhabdus spp., Bacteria Symbiotically Associated with Insect Pathogenic Nematodes of the Families Heterorhabditidae and Steinernematidae
TL;DR: A wide range of micro-organisms, including yeasts, was found to be inhibited by the primary form of Xenorhabdus spp.

The Population Biology of Bacterial Plasmids: A PRIORI Conditions for the Existence of Conjugationally Transmitted Factors.
Frank M. Stewart,Bruce R. Levin +1 more
TL;DR: A mathematical model for the population dynamics of conjugationally transmitted plasmids in bacterial populations is presented and its properties analyzed, and a broad set of physical conditions, resource concentrations and dilution rates are predicted.

Polarity of Tn5 insertion mutations in Escherichia coli.
TL;DR: Tn5's ability to turn on distal gene expression is not due to a promoter in its central region and therefore is not dependent on the overall orientation of Tn5 in the operon.

Controlling elements and the gene.
TL;DR: This paper presented at the 1956 Cold Spring Harbor Symposium provides a brief overview of McClintock's thoughts on controlling elements, including suppressor-mutator, or Spm.

Termination Factor for RNA Synthesis
TL;DR: A new protein has been isolated from E. coli which causes specific termination and release of RNA during synthesis in vitro and has been given the name ρ-factor.
Book
The Bacteriophage Lambda.
TL;DR: No wonder you activities are, reading will be always needed, it is not only to fulfil the duties that you need to finish in deadline time, but also to encourage your mind and thoughts.
