Personal Identification by DNA Typing

The short tandem repeat (STR) polymorphisms are highly useful tools for personal identification and paternity testing in forensic practice. Sequence analysis of mitochondrial DNA (Mt DNA) is being used to characterize forensic biological specimens, particularly when there is insufficient nuclear DNA in samples for typing. Bones, teeth and other samples that are severely decomposed may be subjected to Mt DNA analysis. We could successfully apply these techniques to investigate samples from practical forensic cases and confirming their efficacy for forensic practice.
