Salvador Luria essays

Salvador Luria essays Salvador Luria was one of the founders of microbiology, as we know it. He emigrated from here from his native country of Italy in 1940. His work in the United States is his best known. His work on bacteriophage (bacterial virus) here brought up many new topics in bacteriology, biochemistry, and virology. Born in 1912 in Turin, Italy Salvador Luria was born to David Luria and Ester Sacerdote. His father was a well-respected Jewish leader in his hometown. Salvador attended Liceo dAzeglio high school. This was one of Northern Italys most highly recognized schools. After he finished high school he enrolled in medical school at the University of Turin. In medical school he studied with nerve tissue expert Giuseppe Levi. He met Ugo Fano who later taught him calculus and physics in an after school class using astronomy as a base. The influence that Fano had on Salvador was so great that he decided to pursue basic sciences. He decided to go with Radiology, he believed this was the gap between physics and medicine. He received his medical degree in 1935. Although he had received his degree he was not happy. He believed Radiology was the most boring part of the medical world. Salvador was drafted into the Italian Army as a medic. This proved he was not made for a medical career. He was discharged in 1937 and moved to Rome. In Rome he study at the Physics Institute of the University of Rome. He was shown the writings of Max Delbruck, who had boldly stated a gene, was a molecule. Salvador later said that Maxs writings were the Holy Grail of biophysics. While living in an old broken down trolley car in the streets of Rome Salvador started a conversation with a microbiologist by the name of Geo Rita. Geo introduced him to bacteriophage, Salvador believed he could prove Maxs theory. He fled Europe in 1940 when the Nazi war machine was an approaching. He acquired an American visa and came ...

Writing a protocol for genomic DNA extraction and PCR Lab Report

Writing a protocol for genomic DNA extraction and PCR - Lab Report Example blood collection for control experiment was equally undertaken for the purpose with regards to the manufactures protocol . the sampling of the genomic DNA was used as templates for the PCR amplification with specific T .cruzi Mdna primers . Tcz1 and TC z2 and the KDNA primers s35 and s36 . the amplification reaction was run with 200ng templates DNA UNDER the subsequent conditions.0.2 Mm of each primer , 2.5 U Taq DNA Polymerase , 0.2 mM dNTP and 2 mM Mg Cl2 in a 25 ml final volume . the triplicate amplification reaction were performed using the recommendations temperatures for Ndna ( 950C for five minutes , 30 cycles of 950 C for 30 s , 620C for 1 min nd 72 0C for 1 min and final extension at 72 o C for 5 min ) . The amplicons were resolved in the 1.3 % agarose gel The tumor tissue average RFU 0.254 corresponds to 406.25 standard and controls tissue average RFU 0.197corresponds to 275 standards. The curve is gently rises in a direct proportional manner to huge figures. The scale of the graph presents 1 cm representing 125 ng/ul in y-axis while the 1 cm representing the 0.1 in x-axis (Maria & Frank , 10). 22. It is important to remove the supernatant then dry the pellet at the prevailing room temperature. Normally, the DNA do not attach or stick as expected on the walls of the tube following 70% ethanol wash. Caution and extreme should be maintained while to bid avoid any aspirating the pellet In conclusion, the protocol for DNA extraction and the PCR based typically on the main methods takes subsequent steps. In the process of extraction large quantities of the DNA may be necessitate heating briefly at 65oC) for the suspension. The resulting large great molecular weight may undergo several days for proper
