Population Genetics of the Alu Insertion on the PV92 region of Chromosome 16 Abstract: PCR is a laboratory method used to amplify a small‚ specifically targeted‚ amount of DNA. It has three steps‚ the denaturing of the template DNA‚ the annealing of the primers to the DNA templates and the extension of the new DNA by Taq DNA polymerase. The Alu insert on the PV92 region of chromosome 16 is targeted and its frequency is measured according to the Hardy-Weinberg equilibrium in the Vanier HTK population

Using Data Flow Diagrams Data flow diagram is used by system analyst to put together a graphical representation of data processes throughout the organization. It depicts the broadest possible overview of system inputs‚ processes‚ and outputs. A series of layered data flow diagrams may be used to represent and analyze detailed procedures in the larger system. By using combinations of only four symbols‚ the system analyst can create a pictorial depiction of processes that will eventually provide
