Archaeal extrachromosomal genetic elements.
SUMMARY Research on archaeal extrachromosomal genetic elements (ECEs) has progressed rapidly in the past decade. To date, over 60 archaeal viruses and 60 plasmids have been isolated. These archaeal viruses exhibit an exceptional diversity in morphology, with a wide array of shapes, such as spindles, rods, filaments, spheres, head-tails, bottles, and droplets, and some of these new viruses have ...

15 صفحه اولExtrachromosomal elements in the lower eukaryote Leishmania.
Extrachromosomal DNA elements have been identified in wild-type populations of the parasitic protozoan Leishmania. Elements from L. major and L. tropica were detected using orthogonal-field-alternation-gel electrophoresis. They are nonhomologous, supercoiled circular DNA molecules derived from different chromosomes in the Leishmania genome. Electron microscopy revealed that the elements have ve...
متن کاملAnalysis of extrachromosomal Ac/Ds transposable elements.
The mechanism of transposition of the maize Ac/Ds elements is not well understood. The true transposition intermediates are not known and it has not been possible to distinguish between excision models involving 8-bp staggered cuts or 1-bp staggered cuts followed by hairpin formation. In this work, we have analyzed extrachromosomal excision products to gain insight into the excision mechanism. ...
متن کاملEvidence for linear extrachromosomal elements mediating gene amplification in the multidrug-resistant J774.2 murine cell line.
Previous studies from our laboratory have demonstrated specific cytogenetic alterations accompanying development of colchicine resistance in the J774.2 murine cell line and in two sublines (J7.Cl-30 and J7.Cl-100). Although gene amplification is not observed in the parental J774.2 cell line, a approximately 35-fold amplification of the gene for p-glycoprotein (mdr) was noted in the J7.Cl-30 sub...
