The new DNA database represents the samples of ancient human populations

From archaeological findings, whose age ranges from 2 to 30,000 years, scientists gain genetic information, the so-called ancient DNA. New DNA databases are now being cataloged by a new specialized database prepared by a team of experts from the Institute of Molecular Genetics of the Academy of Sciences of the Czech Republic. The database also contains an interactive map of sample localization. It is freely accessible at http://amtdb.org.

Until recently, analysis of samples from old populations was difficult, as samples were damaged by environmental influences. Methodological advances in both the isolation and processing of ancient DNA and sequencing techniques have now made it possible to analyze ever-increasing samples.

The database of the ancient mtDNA database focuses on the so-called mitochondrial DNA (mtDNA), which is the DNA found in the mitochondria, i. in organelles, due to cellular respiration, energy-rich adenosine triphosphate is produced in society. This mitochondrial DNA is derived from maternal lines and represents one of the classic genetic traits. No additional information available.

Source of information not only for professionals

The new database, which contains information from the Department of Genomics and Bioinformatics Institute of Molecular Genetics, contains more than 1100 samples of full mtDNA and a set of identifiers. These include, for example, the place of finding, dating, details of archeology or culture.

All information from the database is free to download. The database is to serve as a tool for experts in DNA research and analysis and related fields (archeology, anthropology, genetic genealogy). It is also a useful source of information for everyone interested in the history of populations not only in Central Europe.
