The original recipe for gene soup may have been simple—rain, a jumble of common molecules, warm sunshine, and nighttime cooling. Then add a pinch of thickener.
A new study could explain why DNA and not RNA, its older chemical cousin, is the main repository of genetic information. The DNA double helix is a more forgiving molecule that can contort itself into different shapes to absorb ...
New research suggests that the sugar ribose - the "R" in RNA - is probably found in comets and asteroids that zip through the solar system and may be more abundant throughout the universe than was previously thought.
Viruses have proven to be wily foes. Attempts to fend off viruses causing even the common cold or flu have failed, and new viral outbreaks such as dengue, Ebola or Zika continue to elude drugs.
Genetic material from ancient viral infections is critical to human development, according to researchers at the Stanford University School of Medicine.
Panoramix: Protein named for comic book hero guides gene-silencing machinery to sites of havoc-causing transposons
Organisms from bacteria to humans must defend themselves against parasitic genetic elements called transposons, and the stakes are high. These pieces of DNA, which disrupt genes by jumping around in the genome, can cause ...
