DNA replication dynamics in cells from higher eukaryotes follows very complex but highly efficient mechanisms. However, the principles behind initiation of potential replication origins and emergence ...

As illustrated with OnScreen Gene Transcription in our May 1 column, OnScreen Science now has a few very nice iPad apps to teach students about DNA and RNA. The OnScreen DNA Model app was the original ...

Scientists have used 3D models to break down the DNA behavior of cancer cells, in a breakthrough new study which could revolutionize treatment for the disease. Scientists have used 3D models to break ...

DNA can be programmed to self-assemble into high molecular weight 3D assemblies with precise nanometer-scale structural features. Although numerous sequence design strategies exist to realize these ...

Biological engineers have created a new computer model that allows them to design the most complex three-dimensional DNA shapes ever produced, including rings, bowls, and geometric structures such as ...

In a first, researchers have worked out a way to unravel and model the tangled, 3D structures of intact mammalian genomes from individual cells. The new method, published Monday in Nature, could help ...

Scientists have created an unprecedented 3-dimensional structural model of a key molecular "machine" known as the BAF complex, which modifies DNA architecture and is frequently mutated in cancer and ...

In a complex called chromatin, long strands of DNA in cells’ nuclei are tightly wrapped around a scaffolding of proteins, like a rolled-up ball of yarn. A new study by Weill Cornell Medicine ...

Marvel at the tiny nanoscale structures emerging from research labs at Duke University and Arizona State University, and it's easy to imagine you're browsing a catalog of the world's smallest pottery.
