DNA Technique

DNA is a very unique technique and a general representation of various types. The process of DNA technique is simple in which firstly the sample is collected either by the lab officials or the police. The collected sample is extracted by breaking the DNA sample into its nucleus to identify the male and female contributors.

A process of quantation is executed where the DNA is measured in the sample. The DNA present is amplified for further testing. After amplification the DNA is detected and then interpreted by comparing the tested results with previous samples and data.

The Sample test Results i.e. STR is tested in multiple DNA tests out of those the common are Minni STR Testing, Low copy Number DNA testing, Y - chromosome testing MtDNA i.e. Mitochondrial DNA Testing (Bennett, 1995).

Use of DNA in Law

DNA results produced are used in various law cases which are of robbery, murder and sexual assault and harassment cases which include physical assault, rape ...
