In cells, the DNA helix is often overwound, causing a phenomenon known as supercoiling. In the nucleus, DNA forms a complex with proteins. This complex is called chromatin and is formed when the ...

Researchers harness the power of the world’s most advanced supercomputers to simulate the inner workings of cellular machinery that repairs DNA and helps prevent life-threatening diseases. Sunburn and ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures ... each working together in a complex symphony of interactions. With the exception of red blood cells ...

New research pioneered by The University of Western Australia is shedding light on the intricate dance between proteins, DNA ...

For DNA to replicate, the helix must first unwind and break the ... could harness similar energy-efficient mechanisms to perform complex, force-driven tasks," he said.

Franklin, working mostly alone, found that her x-ray diffractions showed that the "wet" form of DNA (in the higher humidity) had all the characteristics of a helix. She suspected that all DNA was ...

"The DNA double helix is one of the most recognizable molecular ... to block or enhance the activity of a particular protein ...

The findings visualize for the first time a molecular complex—called CTF18-RFC in ... turning a single DNA helix into two. Much of this work falls to enzymes called polymerases, which assemble ...
