A Short Tandem Repeat (STR) analysis is one of the most useful methods in molecular biology which is used to compare specific loci on DNA from two or more samples. A short tandem repeat is a microsatellite, consisting of a unit of two to thirteen nucleotides repeated hundreds of times in a row on the DNA strand. STR analysis measures the exact number of repeating units. The probes are attached to desired regions on the DNA, and a polymerase chain reaction (PCR) is employed to discover the lengths of the short tandem repeats. | A Short Tandem Repeat (STR) analysis is one of the most useful methods in molecular biology which is used to compare specific loci on DNA from two or more samples.

STR-analysis is mainly used for forensic analysis and proof of kinship, e.g. a paternity test. | STR-analysis is mainly used for forensic analysis and proof of kinship, e.g. a paternity test. | ||
Julian Chollet is a (no)mad scientist, curious student and informal teacher with a background in molecular biology. He is working on the endless and underexplored biodiverity of microbes, fungi and phages - with the aim to liberate the world from microphobia through workshopology, fermentation and microscopy. His current main project focuses on creative learning environments and public participation in science with emphasis on the invisible world. https://mikrobiomik.org/en |
