...common DNA traits and which did not. The data they derived from studying nuclear genes clearly identified marsupials (kangaroos, opossums, etc.) as having a common evolutionary background with eutherians (humans, pigs, etc.), and monotremes (platypus, echidna) as having evolved separately. Jirtle said these ...

When he discovered that phenothiazines were derived from methylene blue, a dye used in England in the 1850s, he examined other derivatives of the dye and determined that one, quinacrine, had a similar tricyclic scaffold and the same side chain structure as chlorpromazine. Whether further research int...
