Analyses of three meteorites suggest that nucleobases, the crucial components of DNA, could have formed in space and then fallen to Earth.

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.

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 ...

Simple chemical reactions involving ammonia, water and hydrogen cyanide — all ingredients found in meteorites — produced the wide range of nucleobases the scientists found in the space rocks.

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 ...

The full set of five nucleobases joins a growing list of compounds crucial for life that have been detected in meteorites and comets.

An experiment shows that one of the basic units of life -- nucleobases -- could have originated within giant gas clouds interspersed between the stars.

DNA is composed of nucleobases represented by the letters A, T, G and C. But in a bacteriophage, another base, represented by the letter Z, exists. Scientists have now elucidated the biosynthesis ...

Nucleobases are at least as important to life as amino acids, Callahan says, and, until now, no one had found nucleobases in meteorites that couldn’t potentially have been contaminants from Earth.
