The question of how life could have emerged is one of the most long-standing mysteries in science. In a new study, the ...

Adenine and guanine, the two most common purines in DNA and RNA, share this core structure, which is crucial for forming the base pairs in nucleic acids. (Image: Wikimedia Commons, Public Domain) ...

by destroying RNA, a molecule that carries out DNA's instructions. Two years ago, components of the RNA silencing machinery were shown to be absolutely required for forming heterochromatin ...

The new study, funded in part by the National Institutes of Health and published June 18 in Cell Chemical Biology, showed ...

RNA splicing typically depends upon both basal and regulatory components. Whereas the basal proteins are necessary for any splicing event, the regulatory elements modulate the process and lead to ...

For the first time, scientists have identified the RNA component of telomerase enzymes from land plants, which study author Dorothy Shippen described as an "intermediate structure" between humans ...

Alongside DNA, life uses a molecule called RNA for making proteins and doing other odds jobs inside cells. RNA is also made of a long string of bases: guanine, cytosine and adenine (like DNA), but ...

Aided by RNA origami, the Heidelberg synthetic biologist and her team succeeded in creating an essential structural component of synthetic cells -- an artificial cytoskeleton.
