When we think about genetic inheritance, we usually leap to DNA, the four-letter code containing the instructions for building a living organism. Scientists know that DNA encodes everything from hair ...

Forty years ago, a postdoctoral researcher named James McGrath who would go on to spend more than three decades as a clinical geneticist and research scientist at Yale, made a discovery that advanced ...

DNA transcription is the vital first step needed for switching on our genes. For a gene to be switched on, it must be acted upon by an enzyme called RNA polymerase. This is a molecular machine which ...

Scientists have long known that the DNA code in genes is not the only way to pass genetic traits from parents to offspring. "Epigenetic" marks—chemical modifications to DNA that don't change the DNA ...

The COVID-19 pandemic gave us tremendous perspective on how wildly symptoms and outcomes can vary between patients experiencing the same infection. How can two people infected by the same pathogen ...

University of Queensland researchers have discovered a mechanism in DNA that regulates how disease-causing mutations are inherited. Dr. Anne Hahn and Associate Professor Steven Zuryn from UQ's ...

Eating Disorders’ Genetic Risk Factors Explored In New Study. Here Are Some Ways To Seek Help If You're Struggling ...

Two disorders with big names—trichotillomania (repeated hair-pulling) and excoriation disorder (repeated skin-picking)—were ...

"Our journey began with a fundamental question about the genetic underpinnings of ADHD," explained the study authors in a blog post about the paper. "While genome-wide association studies have ...

Lamia Wahba is studying how information outside the genetic code can pass between generations and what that means for evolution and disease. When we think about genetic inheritance, we usually leap to ...
