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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
