DNA’s chemical cousin, RNA, was the messenger that carries DNA instructions from the double helix in the cell’s nucleus to ...

Remnants of the RNA world also appear to be central to modern life. Key molecules such as ATP and NADH are derivatives of RNA components, and RNA appears to catalyze a key step in the production ...

This finding didn’t necessarily favor the RNA World hypothesis. In fact, it was, potentially, compatible with the RNA-DNA World hypothesis, which the Scripps Research team found plausible.

RNA-binding proteins use a dual binding mechanism involving zinc finger (ZnF) domains and intrinsically disordered regions ...

RNA is formed by linking molecules of ribose (a monosaccharide) with phosphate groups that bind to four types of nitrogenous bases: adenine (A), guanine (G), cytosine (C) and uracil (U).

Known as the RNA World Hypothesis, the idea has courted controversy. One of the problems with the theory is that it’s not clear how RNA could have formed spontaneously on a prebiotic Earth.

RNA World is a distributed supercomputer that uses Internet-connected computers to advance RNA research. This system is dedicated to identify, analyze, structurally predict and design RNA ...

"The RNA world is widely thought to be a stage in the origin of life," says Nagoya University biomolecular engineer Keiji Murayama. "Before this stage, the pre-RNA world may have been based on ...
