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 ...

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 ...

In their latest study, published in Nature Communications, the team has built a computer model of a critical NER component called the pre-incision complex ... twists the DNA helix to make the ...

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 ...

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 ...

resulting in adoption of an RNA-like A-form helix, again echoing the findings for the HuLig1-DNA cocrystal. A metal-driven mechanism was revealed by our recent crystal structure of Naegleria gruberi ...

Not all DNA is in the double helix form described in textbooks since the 1950’s. Quadruple helix DNA, also known as G-quadruplex DNA, was identified in the human genome several decades ago, and ...

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

Following is a transcript of the video. Manny: Commercial DNA tests have been a huge trend lately. They were some of the most popular holiday gifts last year. Which makes sense, there's so much ...
