We have found amino acids in meteorites, hints of nucleobases, the genetic code letters, but the results were always suspect, because we know that as soon as a meteorite lands on earth, it gets ...

So, what did we find? Among the most exciting discoveries in the sample are all five of the nucleobases that serve as the code for DNA and RNA.

Scientists report the detection of amino acids, polycyclic aromatic hydrocarbons, ammonia and other compounds, as well as a variety of salts, including sodium carbonates, phosphates, sulfates, and ...

If it's been a while since you've seen Andrew Niccol's sci-fi film Gattaca and need a refresher about where its title comes ...

CRC handbook of nucleobase complexes : transition metal complexes of naturally occuring nucleobases and their derivatives ...

Both nucleobases and sugars are thought to be essential to the origin of life since they are building blocks of RNA and DNA. However, there is a longstanding belief that nucleobases and sugars cannot ...

DNA And RNA Bases, "Missing" Building Blocks Of Life On Earth, Found On Meteorites The missing essential nucleobases cytosine and thymine have been found in meteorites for the first time.

Organic molecules, including uracil and niacin, have been detected in samples collected by Japan’s Hayabusa2 mission from the near-Earth asteroid Ryugu. Uracil is a component of RNA while niacin ...
