DNA sequence data is an indispensable source of research information in biology. But not all data are reliable. Almost 10% of all fungal DNA sequences are, for example, incorrectly identified to species level. A international team of researchers, with it’s core at the University of Gothenburg, Sweden, has therefore prepared a guide to assist the scientific community in the quality control process.
A new scientific study sees the researchers putting together a number of guidelines to help other researchers to ensure a high level of quality among their newly generated DNA sequences.
DNA sequences make it possible to study biological samples and environments at a level of detail that traditional tools, such as microscopes, cannot provide. It is, for example, possible to investigate what species are present in seemingly barren substrates such as soil and seawater. Such studies often reveal an astonishing and hitherto unimagined diversity, and biology has made major advances as the use of DNA-based methods has become more widespread.
