|Forensic analysis can be classified into three distinct areas which are forensic DNA analysis, trace evidence, and drugs and poisons. During 1985 DNA analysis was used in forensic investigation and now also it is used in forensic science to identify the individual involved in a crime investigation. Today the forensic DNA analysis has become one of the most fast growing areas in forensic science because in modern time various technologies and genetic markers have been developed which include short tandem repeat (STR) typing with fluorescence-based detection. This technique is now used universally in forensic DNA laboratories. The difficulties like badly degraded and damaged DNA samples can also be solved by using reduced-sized STR or minSTR.
Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
