Chemical evolution: Progenitors of the living world
by
•RNA was probably the first informational molecule. Now chemists have demonstrated that alternation of wet and dry conditions could have sufficed to drive the prebiotic synthesis of the RNA nucleosides …read more Source:: Science
Spaghetti-like, DNA ‘noodle origami’ the new shape of things to come for nanotechnology
by
•Scientists have invented a major new advance in DNA nanotechnology. Dubbed ‘single-stranded origami,’ their new strategy uses one long, thin noodle-like strand of DNA, or its chemical cousin RNA, that …read more Source:: Science
RNA discovery could help boost plant heat, drought tolerance
by
•The discovery of a RNA that can increase drought and salt tolerance in thale cress could illuminate a new research approach and hold implications for other plants, including food crops. …read more Source:: Science
Fix for 3-billion-year-old genetic error could dramatically improve genetic sequencing
by
•Researchers found a fix for a 3-billion-year-old glitch in one of the major carriers of information needed for life, RNA, which until now produced errors when making copies of genetic …read more Source:: Science
New CRISPR system for targeting RNA
