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 ...

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 ...

In 1995, with the Human Genome Project underway, sequencing was all the rage. Scientists working on the project cloned short fragments of the whole genome and used Sanger sequencing to determine the ...

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 ...

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 ...

Scientists have observed DNA molecules overcoming electrical repulsion to zip together. Positively charged metal ions act as ...
