What was done
The authors conducted a narrative review of the use of human mitochondrial DNA (mtDNA) in forensic science. The review outlines the biological characteristics of mtDNA, its forensic applications, relevant sequencing methodologies, and case examples from the forensic literature.
What was found
The abstract reports no empirical numbers or quantitative findings. It highlights that when nuclear short tandem repeat (STR) typing fails due to low DNA quantity or degradation, mtDNA provides a viable alternative for human identification owing to its key biological attributes: high copy number, small circular structure, high mutation rate, maternal inheritance, and absence of recombination.
Why it matters
The paper summarizes the technical and biological rationale for applying mtDNA analysis to forensic investigations where conventional nuclear DNA profiling is unviable due to sample degradation.
Limits
As a narrative review, the paper introduces no new empirical data, meta-analytic pooling, or structured systematic search criteria. The abstract does not provide quantitative diagnostic accuracy, error rates, or direct comparisons of sequencing technologies.
