if glucose can get a molecule catto can we see the nucleotide bases
@ciaaik has made designs for them!
Compounds are a bit weird to do these little icons for. At the bottom left of each icon are the compound's constituent elements, and on the top left are their respective numbers of atoms in the molecule.
For anyone who doesn't know who these guys are: the first four - Adenine, Cytosine, Guanine and Thymine - are the building blocks of DNA and the letters of its genetic language, while the last one, Uracil, replaces Thymine in DNA's more ancient and primitive sibling RNA.
When thymine is replaced by uracil
Heheh.. Im so funny:) sent to my gf and she didn’t even know what U was… lameeee (aparently not everybody knows the bases of rna and dna off the tops of their heads??)

An article published in the journal "Nature Communications" reports the discovery of uracil, one of the bases of RNA, and niacin, i.e. vitamin B3, in the samples of asteroid Ryugu brought back to Earth by the Japanese Hayabusa 2 space probe. A team of researchers led by Yasuhiro Oba of Japan's Hokkaido University developed an analytical technique to identify compounds in concentrations between parts per billion and parts per trillion to analyze just over 5 grams of samples.
