Unexpected slowdowns or spikes in this signal were often interpreted as knots in DNA. But now, a new study published Aug. 12 ...

DNA doesn’t knot under stress. A new study finds it coils into plectonemes, reshaping models of genome mechanics. For decades ...

The visible effects of ageing on our body are in part linked to invisible changes in gene activity. The epigenetic process of ...

DNA is a linear biopolymer, a compound biomolecule in the form of a double helix. Polymers are made of monomers, and in DNA, these monomers are called nucleotides or nucleobases. The enzymes that ...

Spatial DNA organization forms first, then the rest Date: May 22, 2019 Source: Hubrecht Institute Summary: The fundamental organization of the DNA in active and inactive compartments arises ...

Broken DNA strands are usually associated with cancer, and inflammation is linked to aging. But a new study in mice suggests that breaking and repairing DNA in neurons paves the way for long-lasting ...

DNA can shape itself into many forms to achieve its purposes in life. The crystal structure of the junction between two of its forms provides insight into how DNA might accomplish some of these ...

In a world first, researchers have identified a new DNA structure -- called the i-motif -- inside cells. A twisted 'knot' of DNA, the i-motif has never before been directly seen inside living cells.

DNA incorporating Diaminopurine is called Z-DNA. We've known since 1979 that it exists in nature in the form of a single virus called S-2L, which infects cyanobacteria.

In a world first, Australian researchers have identified a new DNA structure -- called the i-motif -- inside cells. A twisted 'knot' of DNA, the i-motif has never before been directly seen inside ...
