DNA Evidence: Basics of Analyzing Overview of Steps in Analyzing DNA Evidence
ثبت نشده
چکیده
Several basic steps are performed during DNA testing regardless of the type of test being done. The general procedure includes: 1) the isolation of the DNA from an evidence sample containing DNA of unknown origin, and generally at a later time, the isolation of DNA from a sample (e.g., blood) from a known individual; 2) the processing of the DNA so that test results may be obtained; 3) the determination of the DNA test results (or types), from specific regions of the DNA; and 4) the comparison and interpretation of the test results from the unknown and known samples to determine whether the known individual is not the source of the DNA or is included as a possible source of the DNA.

A new Schiff base ligand (L) obtained by the condensation reaction of N-acetylaceto-otoluidineand 2-aminopropanoic acid (an amino acid), is used to synthesize four mononuclearcomplexes of [MLCl] and [ML2] types (where M = Cu(II) and Zn(II); L = Schiff base) bykeeping the metal and ligand ratio as 1:1 and 1:2 respectively. This ligand and its complexeshave been characterized on the basis of diff...
