Sentences with phrase «nucleobases found»

These peptides interact with the same nucleobases found in DNA, but each nucleobase is bound to an organic compound known as a thioester.

Figuring out how adenine and uracil (nucleobases found in RNA today) combined with the sugar ribose (corresponding to the «R» in RNA) could answer one of the great questions of chemical evolution.

Martins found the answer by extracting two molecules from the meteorite: uracil, a nucleobase found in RNA, and xanthine, an intermediate in the synthesis of DNA and RNA.
