When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication ...

Huge sections of the human genome are made up of highly repetitive sequences, areas where bases like ATATAT repeat in very long strings. For many years, scientists wrote these repetitive sequences off ...

Scientists have found that non-coding 'junk' DNA, far from being harmless and inert, could potentially contribute to the development of cancer. Their study has shown how non-coding DNA can get in the ...

The universal features that define genomic regions acting as replication origins remain unclear. In this study, we mapped a set of origins in Trypanosoma brucei using stranded short nascent strand ...

To our immune system, a potentially lifesaving gene therapy can look a lot like a dangerous infection. That's because most ...

Like its viral cousins, a somewhat parasitic DNA sequence called a retrotransposon has been found borrowing the cell’s own machinery to achieve its goals. In a new work appearing online Wednesday in ...

Since the 1990s, nanopores have been used for sequencing strands of DNA. A voltage is applied across the nanopore, which is embedded in a thin lipid membrane, causing a stretch of DNA to thread ...

Zettabytes—that’s 10 21 bytes—of data are currently generated every year. All of those cat videos have to be stored somewhere, and DNA is a great storage medium; it has amazing data density and is ...
