Repeated Sequences

Repeated sequences are stretches of DNA code found in the human genome that contain several copies of the same short sequence of nucleotides. These repetitive regions are important for a variety of biological functions, including gene regulation, understanding genome structure and gene expression. Repeated sequences have been linked to many genetic diseases, such as Fragile X syndrome and Huntington’s disease. They can also play a role in cancer, hemophilia and other medical conditions. In addition, understanding repeated sequences can be useful for creating genetic tests and drug therapies. Research into repeated sequences is helping to improve our knowledge of genetics and the underlying causes of many diseases.
