DNA como ferramenta na genética forense

Abstract

Currently, studies on chromosome markers and forensic genetics have gained notoriety in the area of ​​Molecular Biology for contributing to the elucidation of crimes and paternity investigations. The markers enable greater practicality in experts' routines by providing authentic results to the population, identifying victims through biological samples. The objective of this work is to develop a bibliographical research on molecular markers of the chromosome and forensic genetics, highlighting their importance and limitations, through a narrative review. Where we can conclude that molecular markers are useful tools in molecular biology and genetics, being used to specifically identify any living organism. The use of chromosome markers can be a viable alternative in situations where other sources of DNA are unavailable or of low quality. The evaluation of chromosome markers has become an important resource in forensic genetics, not only in resolving legal cases, but also in generating data that make up the characterization of a population in the face of human evolution. With the evolution of genetic sequencing techniques, it is possible to obtain more and more information, increasing the precision and reliability of the results obtained.
