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 ...

Inside cells, DNA twists and coils itself into a variety of different secondary structures—including i-motifs (iMs) and ...

In an article published in Nature Microbiology, scientists reveal the existence of numerous new lineages of mirusviruses, ...

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 ...

Circular DNA, thought to be an accidental byproduct, is borrowing the cell’s DNA repair mechanisms to copy itself DURHAM, N.C. -- Like its viral cousins, a somewhat parasitic DNA sequence called a ...

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 ...

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 ...

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 ...
