DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

Further analyses of the nucleotide bases preceding and following these point mutations suggested they were caused by two types of human editing deaminase enzymes, called APOBECs and ADARs.

Similar to DNA, RNA is formed of a strand of varying combinations of four different nucleotide bases: uracil, cytosine, adenine and guanine. How these bases are arranged determines the code that ...

Oba said uracil and niacin were found at both landing sites on Ryugu, which is about a half-mile (900 meters) in diameter and is classified as a near-Earth asteroid.

Uracil and other organic molecules have previously been found in these meteorites, but there has been no way to rule out the possibility that some of the molecules had a terrestrial origin.
