Scientists have tracked down an elusive 'tangled knot' of DNA

It's DNA, but not as we know it. 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 ...

New molecule has potential to help treat genetic diseases and HIV

(PhysOrg.com) -- Chemists at The University of Texas at Austin have created a molecule that's so good at tangling itself inside the double helix of a DNA sequence that it can stay there for up to 16 days before the DNA liberates ...

DNA and the 'magic rings' trick

(PhysOrg.com) -- A new study from UC Davis shows how, like a conjuring trick with interlocking rings, two interlocked pieces of DNA are separated after DNA is copied or repaired. The finding was published online Oct. 10 in ...

Novel DNA architecture for nanotechnology

The DNA structure as revealed by Watson and Crick is pivotal to the stability and replication of the DNA double helix. Replacement of the DNA base-pairs with other molecular entities is providing new functions for DNA and ...

Biochemists uphold law of physics (w/ Video)

Experiments by biochemists at the University of California, Davis show for the first time that a law of physics, the ergodic theorem, can be demonstrated by a collection of individual protein molecules—specifically, a protein ...

Art with DNA—digitally creating 16 million colors by chemistry

The DNA double helix is composed of two DNA molecules whose sequences are complementary to each other. The stability of the duplex can be fine-tuned in the lab by controlling the amount and location of imperfect complementary ...

DNA damage: The dark side of respiration

(Phys.org) —Adventitious changes in cellular DNA can endanger the whole organism, as they may lead to life-threatening illnesses like cancer. Researchers at LMU now report how byproducts of respiration cause mispairing ...

How molecular scissors cut in the right place

A research group at Uppsala University has found out how CRISPR-Cas9—also known as 'molecular scissors'—can search the genome for a specific DNA sequence. Cas9 already has many applications in biotechnology and is also ...
