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 ...

Knowing how human DNA changes over generations is essential to estimating genetic disease risks and understanding how we evolved. But some of the most changeable regions of our DNA have been ...

Haoyu Cheng, Ph.D., assistant professor of biomedical informatics and data science at Yale School of Medicine, has developed ...

Add Yahoo as a preferred source to see more of our stories on Google. A SickKids led study has found that tiny repeated DNA segments called short tandem repeats vary not only in length but also in ...

The newest DNA sequencing technology from Swiss multinational Roche doesn’t measure DNA directly but in fact analyzes a different polymer altogether. The technology is not yet available for sale, but ...

Every living organism has its own genetic "blueprint": the source code for how it grows, functions and reproduces. This ...

Advances in DNA sequencing have revealed something surprising—not everyone with the same genetic change develops the same ...

Epigenetics is the study of various heritable alterations that control gene expression without changing the DNA sequence. 1 The name epigenetics comes from the Greek prefix “epi”, which means on top ...

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 ...

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 ...

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 ...
