Audrey Stevens Niyogi
Audrey Stevens Niyogi (July 21, 1932February 28, 2010) was an American biochemist, best known as a co-discoverer of RNA polymerase. Early life and education Audrey Stevens Niyogi was born on a farm near Leigh, Nebraska, the third child of Louise and John Stevens. She had an older brother Travis and a fraternal twin sister Ardyce. Later the family moved to another farm about 10 miles from Wayne, Nebraska. When teenagers, Audrey and Ardyce boarded with a family in town so they could attend high school without the long commute. Audrey pursued the study of chemistry following in her older brother’s footsteps, who pursued a career in organic chemistry. After 2 years at the Nebraska State Teachers College (now Wayne State College), she earned her BS in chemistry from Iowa State College (now Iowa State University) in 1953, and her PhD in biochemistry from Case Western Reserve University in 1958. Scientific career While a postdoctoral researcher at NIH, Audrey Stevens independent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

T4 Bacteriophage
Escherichia virus T4 is a species of bacteriophages that infect ''Escherichia coli'' bacteria. It is a double-stranded DNA virus in the subfamily '' Tevenvirinae'' of the family '' Straboviridae''. T4 is capable of undergoing only a lytic life cycle and not the lysogenic life cycle. The species was formerly named T-even bacteriophage, a name which also encompasses, among other strains (or isolates), Enterobacteria phage T2, Enterobacteria phage T4 and Enterobacteria phage T6. Use in research Dating back to the 1940s and continuing today, T-even phages are considered the best studied model organisms. Model organisms are usually required to be simple with as few as five genes. Yet, T-even phages are in fact among the largest and highest complexity virus, in which these phage's genetic information is made up of around 300 genes. Coincident with their complexity, T-even viruses were found to have the unusual base hydroxymethylcytosine (HMC) in place of the nucleic acid base ...

People From Wayne, Nebraska
The term "the people" refers to the public or Common people, common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of Person, persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Declaration on the Rights of Indigenous Peoples, Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independence, independent sovereignty and therefore secession.

Anti-sigma Factor
Introduction Anti-sigma factors are small Protein, proteins that bind to Sigma factor, sigma factors and inhibit Transcription (genetics), transcriptional activity in regulating prokaryote gene expression. Anti-sigma factors have both a sigma-binding domain and a sensory/signaling domain; this allows them to respond to signals inside and outside the cell. Anti-sigma factors have been found in several bacteria, including ''Escherichia coli'' and ''Salmonella'', and viruses such as the T4 bacteriophage. Anti-sigma factors have an antagonistic effect on sigma factors. Each sigma factor has an associated anti-sigma factor that regulates it. These anti-sigma factors are divided into Cytoplasm, cytoplasmic-bound anti-sigma factors and inner membrane-bound anti-sigma factors. The differences in these sigma factors are where in the cell they are bound. Cytoplasmic-bound anti-sigma factors include FlgM, DnaK, RssB, and HscC. Inner membrane-bound anti-sigma factors, also called extra-cytop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
