Construction of consecutive deletions of the Escherichia coli chromosome
The minimal set of genetic information necessary and sufficient to sustain a functioning cell contains not only trans-acting genes, but also cis-acting chromosomal regions that cannot be complemented by plasmids carrying these regions. In Escherichia coli (E. coli), only one chromosomal region, the origin of replication has been identified to be cis-acting. We constructed a series of mutants wi...
متن کاملconstruction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...

15 صفحه اولInfluence of chromosome structure on the frequency of tonB trp deletions in Escherichia coli.
The frequency of tonB trp deletions varies in different strains and substrains of Escherichia coli. Studies with chromosomal hybrids constructed by transducing various segments of the cysB-trp-suIII region from K-12(Ymel) into K-12(W3110) indicate that the characteristic low deletion frequency of K-12(Ymel) is determined largely by the (genetic) structure of the trp-suIII region of the chromoso...
متن کاملStimulation of deletions in the Escherichia coli chromosome by partially induced Mucts62 prophages.
Deletion of bacterial DNA fragments is stimulated in induced Mucts62 lysogens. The host genes located proximally to the prophage are more frequently lost than those which are unlinked to the Mu genome. Genes located on either side of a Mu genome are deleted in the same manner. Like the other Mu-induced rearrangements, this process is recA independent and requires the participation of Mu DNA, as...
