Abstract:
Explants (7.5±2.5 mm) cut from stems and roots of 3-week-old Eustoma grandiflorum Grise, (lisianthus) cv. Glory White seedlings were bombarded with plasmid pBI221, which harbors the uidA gene encoding β-glucuronidase (GUS) driven by the cauliflower mosaic virus (CaMV) 35S promoter. More than 800 blue spots of GUS-expressing cells were observed per 90 explants. Explants bombarded with pARK22 harboring the bar gene encoding phosphinothricin acetyltransferase driven by the CaMV 35S promoter were selected for bialaphos resistance. Putative transgenic plants were obtained about 3 months after bombardment. Southern blot analysis of putative transgenic plants revealed the presence of the bar gene in their genome.

Bacterial Transformation
Griffith made an unexpected discovery when he killed the pathogenic strain and mixed its remains with the live, non-pathogenic strain. Not only did the mixture kill host mice, but it also contained living pathogenic bacteria that...

The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...
Transformers
The iron core has a substantial relative permeability. Therefore, the magnetic field lines generated due to the current in one winding are almost entirely confined within the core, such that the same magnetic flux permeates each turn of both...
