Why is the heart slightly on the left side of the body for most people? Why is DNA almost always a right-handed helix? Same with alpha helices, the building blocks of proteins. Chirality ...

Z-DNA exists transiently in short stretches of up to 100 base pairs within some right-handed DNA molecules. The site where the DNA molecule switches chirality is called a B-Z junction. At this point ...

The DNA molecule was composed of the traditional sugar backbones and nucleotide pairs, but rather than the well-known right-handed spiral of the double helix structure, famously discovered by Watson ...

Once access has been gained, Rad51 polymerizes on the DNA strand to form what is called a presynaptic filament, which is a right-handed helical filament containing six Rad51 molecules and 18 ...

David Newton, 70, was charged in 2024 after DNA matching his profile was found on nail clippings taken from Mrs Crown's right hand in 2013. Mr Newton, who lived near Mrs Crown in Wisbech ...

Cady tried to hide a deep cut on his right hand and, when asked about it, gave "inconsistent explanations." Although investigators collected DNA samples from Cady's cut, it provided "no major ...

The Bennu discovery helps to illuminate how, early in the Solar System’s history, asteroids and other planetary building blocks were not just “lumps of stone and ice, but active ‘living’ objects”, ...
