Humans have about 3 billion DNA bases in their genetic makeup. However, most of it does not encode for protein.

Red arrows indicate the nuclear spin axes at the positions of the N3 nitrogen atoms on the guanine (G) bases. Due to the helical structure of DNA, there is an angular deviation in the orientation of ...

Add Yahoo as a preferred source to see more of our stories on Google. A Tokyo team built a neutral PEG-DNA complex that boosted gene expression in mouse muscle, avoiding cation-linked inflammation.

Scheme showing the structure of cytosine, 5-methylcytosine, and 5-hydroxymethylcytosine. Adding a methyl group to the DNA base cytosine represses gene expression in mammalian cells. To remove the ...

Scientists from the RNA Institute at the University of Albany (UAlbany) have developed new methods for designing and assembling DNA nanostructures that enhance their potential for use in various ...

On Monday, a paper announcing that all four DNA bases had been found on an asteroid sparked a lot of headlines. But many of the headlines omitted a key word needed to put the discovery in context: ...

Getting DNA into a living cell sounds simple, until you remember the cell’s outer membrane acts like a guarded wall. DNA strands carry a negative charge, and they do not cross that wall easily. So for ...
