We keep finding the raw material of #DNA in #asteroids—what's it telling us?
There are four #nucleicacids (A, T, C, and G in DNA; A, U, C, and G in #RNA), and one is always attached to each of sugars in backbone. The order of the bases along the backbone is what carries genetic information, enabling life as we know it. It’s been hypothesized that, before life evolved, the order of bases along RNA molecules determined the sorts of chemical reactions they could catalyze.

Our newest publication is out!
We showed that the yeast core factor (CF) binds and specifically recognizes promoter DNA in a two-step process, after which it will recruit RNA Polymerase I, inducing DNA bending and melting to start the transcription process.

🎨 🧬 Take a look at the extraordinary watercolor paintings in the Molecular Landscapes Gallery by David S. Goodsell.
The watercolor paintings of David S. Goodsell integrate information from #StructuralBiology, #Microscopy and #Biophysics to simulate detailed views of the molecular structure of living cells. #Proteins, #NucleicAcids, and #LipidMembranes are shown; #SmallMolecules, ions, and water are omitted for clarity.
