REGULAR EXPRESSIONS AND IT’S APPLICATIONS REGULAR EXPRESSIONS A regular expression is a specific pattern that provides concise and flexible means to "match" (specify and recognize) strings of text‚ such as particular characters‚ words‚ or patterns of characters. Common abbreviations for "regular expression” include regex and regexp. It is a Compact mechanism for defining a language. OPERANDS OF REGULAR EXPRESSION The empty string ε Single characters of the underlying

Summary The book The Selfish Gene is about the acts of species and how they can affect what the next generations may act more like. Animals that act altruistically and sacrifice themselves for their own can’t pass on their behaviors. Animals that act selfishly and continue living can pass on their selfish acts. Our genes can tell us to act selfishly; we don’t need to obey though. A gene is defined as a part of a chromosome‚ the size undefined‚ in this book. It is described how life might have come

history of tumor growth and development. Genetic changes accumulate in the form of mutations‚ activation of proto-oncogenes‚ or the loss of tumor suppressor genes that could promote tumor progression‚ invasion‚ and metastasis; this process provides a rational basis for targeting one or more critical genetic defects in cancer cells by using gene-mediated therapy approaches(Parks & Bramson‚ 1999). Glioblastoma is a heterogeneous disease with a spectrum of histopathological characteristics and numerous

Gene Mapping in Ascospore Sordaria Cultures by Recombination Abstract The laboratory experiment demonstrates the process of meiosis using the Sordaria Fimicola fungi. Meiosis is important because it is the process that generates diversity in genetics. A wildtype was crossed with two mutant types: tan and grey. In order to exhibit recombination‚ the sequence of ascospores needed to result in a 2:2:2:2 or 2:4:2 sequence. From the crossover

genomics approach integrated with cellular and in vivo assays‚ we screened a small compound library to identify modulators of IFN-α biological effects. A genomic fingerprint was developed from both ex vivo patient genomic information and in vitro gene modulation from IFN-α cell-based stimulation. A high throughput genomic-based screen then was applied to prioritize 268 small molecule inhibitors targeting 41 different intracellular signaling pathways. Active compounds were profiled further for
