Tiny ‘microlightning’ flashes inside water droplets may have sparked life on Earth - Study says tiny electric discharges ...

Ribonucleic acid (RNA) is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine (G), and uracil (U). RNA is often compared ...

Scientists from Stanford University created the microscopic electrical charges in a lab and mixed them with gases found in ...

In RNA, however, a base called uracil (U) replaces thymine (T) as the complementary nucleotide to adenine (Figure 3). This means that during elongation, the presence of adenine in the DNA template ...

But real lightning would have struck infrequently—and mostly in open ocean, where organic compounds would have quickly ...

The research, conducted by scientists at Stanford University, demonstrates that when water droplets collide and form spray, ...

RNA is formed by linking molecules of ribose (a monosaccharide) with phosphate groups that bind to four types of nitrogenous ...

It is a polymeric molecule composed of nucleotides, each containing a ribose sugar, a phosphate group, and one of four nitrogenous bases: adenine (A), uracil (U), guanine (G), or cytosine (C). RNA is ...

All five nucleobases that make up DNA and RNA have now been detected in meteorite samples ... identified in samples from some of the same meteorites—but also cytosine, uracil, and thymine, supporting ...

including uracil, one of the components of DNA and RNA. The study, published in the journal Science Advances, adds evidence – and a new angle – to the much-disputed Miller-Urey hypothesis ...
