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 ...

In a single experiment, scientists can decipher the entire genomes of many patient samples, animal models, or cultured cells.

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 ...

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 ...

A study published in the journal Science reveals how jumping fragments of human DNA, a type of genetic parasite, destabilize the cancer genome. Unstable genomes are a fertile playground for cancer ...

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 ...
