متن کاملEnergy requirements for specific pair formation during conjugation in Escherichia coli K-12.
are pre-endowed with appendages, called donor pili, which are responsible for specific pair formation (C. C. Brinton, Trans. N.Y. Acad. Sci. 27:1003, 1965); this led us to believe that specific pair formation might occur in the absence of energy metabolism. However, K. W. Fisher (J. Gen. Microbiol. 16:136, 1957), in showing that zygote formation was dependent on active energy metabolism, conclu...
متن کاملTransduction in Escherichia Coli K-12.
SYSTEM of genetic transduction has been discovered in the sexually fertile A K-12 strain of Escherichia coli. This transduction is mediated by lambda, a temperate phage for which K-12 is normally lysogenic. The distinctive features of the lambda-K-12 system include the following: (1) The transductions are limited to a cluster of genes for galactose fermentation. The GaZ loci are closely linked ...
متن کاملModification of conjugation in Escherichia coli K-12 by ultraviolet irradiation.
ONJUGATION in Escherichia coli K-12 results from a sequence of consecutive steps: (1) an effective union between two cells of opposite mating types; (2) a polarized transfer of at least a portion of a male chromosome into the recipient cell, the precise order of transfer depending only on the donor strain utilized; (3) an integration of the genetic information from both parental strains into a ...
متن کاملConjugation in Escherichia coli.
Boyer, Herbert (Yale University, New Haven, Conn.). Conjugation in Escherichia coli. J. Bacteriol. 91:1767-1772. 1966.-The sex factor of Escherichia coli K-12 was introduced into an E. coli B/r strain by circumventing the host-controlled modification and restriction incompatibilities known to exist between these closely related strains. The sexual properties of the constructed F(+) B strain and...
