This image compares three DNA sequencing technologies: Sanger sequencing, Massively Parallel DNA sequencing, and Nanopore DNA sequencing. Sanger sequencing (left) sequences 500-700 bases per reaction ...

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 ...

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

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 technological advancements have allowed us to look at the entire human genome. The genome is the complete set of genetic information encoded in the DNA. Human DNA has around three billion letters ...

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 ...

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

DNA sequencing is one of today's most critical scientific fields, powering leaps in humanity's understanding of genetic causes of cancer, neurodegenerative diseases, and diabetes. One issue facing the ...

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

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 ...
