Investigators have also found nucleobases, key ingredients of DNA, in meteorites before. However, it has been very difficult to prove that these molecules are not contamination from sources on ...

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 ...

The molecules that form our DNA are also found in meteorites, according to a new study. These nucleobases could prove that meteors seeded life on Earth.

For 50 years, scientists have debated whether the components of DNA — the molecule central to all life on Earth — could spontaneously form in space. A new analysis of a dozen meteorites found ...

Evidence is mounting that the key building blocks of life may have been delivered to our home planet from space. Scientists have now identified in meteorites the last two DNA nucleobases that hadn ...

After the formation of nucleobases in outer space, the meteorites would have been able to deliver the molecules to Earth, later becoming the basis of all genetic coding for life. Dr Helena Bates , who ...

Essential building blocks of DNA -- compounds called nucleobases -- have been detected for the first time in a simulated environment mimicking gaseous clouds that are found interspersed between stars.

The experimental findings give new insight on how the nucleobases inside DNA protect themselves from damage induced by ultraviolet light. In addition, the experimental scheme developed will be ...

While none of these compounds are directly part of life’s chemistry, they could be precursors for biologically relevant amino acids and the more complex nucleobases utilized by RNA and DNA.
