Doyle is first seen in a conference room with Dr. John Brand. He is also the first person in the mission who docks Ranger 1 & 2 to the Endurance. Later, he, Cooper, Amelia, and CASE go down to the water planet Miller.
Structure and function of the yeast URA3 gene: expression in Escherichia coli. Rose M, Grisafi P, Botstein D. The expression of the cloned Saccharomyces cerevisiae URA3 gene in Escherichia coli on both plasmid and phage vectors was studied.Isolates of the gene from two different laboratory strains of yeast differ in their ability to be expressed in E. coli in the absence of external adjacent promoters of transcription.The DNA sequence of the two genes was determined and revealed several differences in the DNA flanking the structural gene.One base change alters the Pribnow-box of an E. coli promoter present in the yeast sequences.solates of the gene from two different laboratory strains of yeast differ in their ability to be expressed in E. coli in the absence of external adjacent promoters of transcription. The DNA sequence of the two genes was determined and revealed several differences in the DNA flanking the structural gene.
Abstract. The opportunistic pathogen Candida glabrata causes significant disease in humans. To develop genetic tools to investigate the pathogenicity of this organism, we have constructed ura3 and his3 auxotrophic strains by deleting the relevant coding regions in a C. glabrata clinical isolate.. glabrata is a significant cause of human disease in spite of the fact that it is phylogenetically closely related to the nonpathogenic S. cerevisiae. In this investigation, we used standard one-and two-step disruptions to generate ura3 and his3 auxotrophs in which the coding regions are deleted.
