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 ...

New analytical methods developed at Baylor College of Medicine and collaborating institutions have increased our understanding of how bacteria manage DNA. The methods enabled researchers to uncover ...

Scheme showing the structure of cytosine, 5-methylcytosine, and 5-hydroxymethylcytosine. Adding a methyl group to the DNA base cytosine represses gene expression in mammalian cells. To remove the ...

DNA is more than just the iconic double helix we learned in school—it's a dynamic, complex structure at the heart of life. From high-speed replication to advanced sequencing technologies, scientists ...

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 ...

Nanopore sensors are tiny devices used to detect and analyze individual molecules by measuring ionic changes as the molecules pass through nanometer-scale openings. These sensors are classified into ...

DNA methylation is a key epigenome component that helps dictate how genes are expressed, contributing to normal cell and tissue differentiation during development, as well as the process of biological ...
