In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...

Roche has put forward a new approach to genetic analysis, which it describes as sequencing-by-expansion—a proprietary method that pulls apart the DNA molecule and amplifies the signal of each ...

NEW YORK (WRGB) — Over 600 cases across the U.S. have been solved using genetic genealogy and DNA sequencing. Family trees once thought to be a fun project for the family historian are quickly ...

Tiny repeated stretches of DNA in your genome may quietly shape how your body works, how your brain develops and how you respond to disease. A new study from scientists at The Hospital for Sick ...

DNA can also be demethylated, either through passive or active processes. Passive DNA demethylation occurs when the methylation pattern is not replenished during DNA replication and gradually ...

The sequence pattern matters: Interruptions or “hitches” and loss of these within the C-A-G repeat and C-C-G repeat stretches play a major role as to when symptoms start with loss of interruptions ...

DNA methylation is a highly studied epigenetic modification that is involved in regulating genome function and plays fundamental roles in development and disease. 1 It is linked to a broad range of ...

Newborn babies admitted to the hospital's neonatal intensive care unit (NICU) rely on the quick decisions and rapid action of the medical team responsible for them. DNA testing is critical to ...
