DNA Marker

A DNA marker is a specific segment of DNA with a known location that can be used to identify or differentiate individuals, species, or genetic traits. Think of it as a genetic signpost or a unique barcode within the genome. These markers are useful in various fields, such as forensics, paternity testing, and breeding programs, because they help track genetic inheritance and variations. Essentially, DNA markers serve as reference points in the genome, enabling scientists to study genetic differences efficiently and accurately.
