Little is known about mechanisms that regulate and ensure accurate processing of complex transcription units with long introns. We investigate this in the Ultrabithorax gene of Drosophila. A consensus 5' splice site is regenerated at the junction between the first exon and a small internal exon (mI); this splice site is used in a developmentally regulated(More)
We describe a new method for gene discovery and analysis, CD-tagging, that puts specific molecular tags on a gene, its transcript and its protein product. The method has been successfully tested in two organisms, the haploid unicellular alga Chlamydomonas reinhardtii and the metazoan Drosophila melanogaster. The method utilizes a specially designed DNA(More)
The antioxidant activity of two edible medicinal plants commonly used in Malaysian traditional medicine i.e. Piper sarmentosum (kadok) and Morinda elliptica (mengkudu) were tested for antioxidant activity. The methanolic leave extracts of kadok and mengkudu, at 250ug/ml, were tested using the Xanthine/Xanthine Oxidase (X/XOD) Superoxide Scavenging assay.(More)
to the drug by highly specific translocation events that correspond to the drug mode of action. Observation of these effects was enabled by measuring the proteome dynamics in space and time in individual cells. The present approach provides a window into human cell biology and opens the way for understanding how seemingly identical cells show different(More)
