The authors confirm that telomeres in telomerase-positive cells terminate with 5'-ATC in a Pot1-dependent manner, and demonstrate that this principle holds true in telomerase-negative ALT cells as ...

Most biochemistry labs that study DNA isolate it within a water-based solution that allows scientists to manipulate DNA without interacting with other molecules. They also tend to use heat to ...

which in turn may contribute to DNA strand breaks. Folic acid supplementation has been linked to a reduced risk of breast cancer. However, the review emphasizes that both excessive and deficient ...

DNA topoisomerase 1 is an enzyme present in all organisms, essential for cell proliferation. Its function is based on two catalytic steps: firstly, it cuts and then relinks the DNA, thus relaxing ...

What did the duo actually discover? Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case.

Their search for a live-saving medicine for humans requires DNA samples from three of those creatures, leading them to extract a sample from a pterodactyl egg in a cave, but not before the mother ...

“Love” (Strand Releasing): This Norwegian film about two health care ... “It kind of harkens back to the previous entries in the franchise,” Wang said. “It’s a kid who is a fish out of water who comes ...

DNA i-motif structures are formed in the nuclei of human cells and are believed to provide critical genomic regulation. While the existence, abundance, and distribution of i-motif structures in human ...

We report the design and construction of a nanometer-sized tetrahedron from a single strand of DNA that is 286 nucleotides long. The formation of the tetrahedron was verified by restriction enzyme ...

We report the discovery that cardiac glycosides, natural products in clinical use for the treatment of heart failure and atrial arrhythmia, are potent inhibitors of DNA double-strand break (DSB) ...
