The size discrepancy among thorny skates has been noted for nearly a century, but the issue became especially significant in ...

Since opposite charges attract, the DNA is pulled in toward the histones. A nucleosome is a segment of the DNA wrapped around a core of histones. Here is a view of the double helix -- the subject ...

These groups are called the reading frame. Thus, if the number of bases removed from or inserted into a segment of DNA is not a multiple of three (Figure 4a), the reading frame transcribed to the ...

Sunburns and aging skin are obvious effects of exposure to harmful UV rays, tobacco smoke and other carcinogens. But the effects aren't just skin deep. Inside the body, DNA is literally being torn ...

DNA is a mosaic of genetic fragments passed down through generations, but its clarity diminishes over time. While modern testing can trace ancestry through shared markers, the depth of this insight ...

The Therapeutic DNA Production Services segment consists of the enzymatic manufacture of synthetic DNA for use in the production of nucleic acid-based therapeutics and, the development and sale of ...

Some cut the DNA at that site, using an adjacent DNA-cutting segment of the protein. That modularity could facilitate tool development, allowing researchers to swap useful new features into ...

Researchers at Georgia State University used the Summit supercomputer to study an elaborate molecular pathway called ...
