Natural Nucleobases

Some articles on natural nucleobases, nucleobases:

Nucleic Acid Analogues - Base Analogues - Metal Base-pairs
... with DNA can occur by the formation of non-canonical base pairs from natural nucleobases with participation by metal ions and also by the exchanging the hydrogen atoms that are part of the Watson-Crick base pairing ... Metal complexing has been shown to occur between natural nucleobases ... example is the formation of T-Hg-T, which involves two deprotonated thymine nucleobases that are brought together by Hg2+ and forms a connected metal-base pair ...

Famous quotes containing the word natural:

    “What we know, is a point to what we do not know.” Open any recent journal of science, and weigh the problems suggested concerning Light, Heat, Electricity, Magnetism, Physiology, Geology, and judge whether the interest of natural science is likely to be soon exhausted.
    Ralph Waldo Emerson (1803–1882)
