2. Explain why the ionic refractivity of a bridging and non-bridging oxygen should be different (20...
1. Why the ribozyme interacts with one of the two non bridging phosphate oxygen atoms at the cleavage site, but not via inner sphere coordination with a divalent metal ion at the active site? 2. Why pistol ribozymes do not require inner sphere coordination of divalent metal ions anywhere in the structure, including at the active site? 3. Why the pistol ribozyme contract with one of the two non bridging oxygen atoms in a way that is strongly disrupted by...
Why are many ionic compounds not soluble in water? A. They are non-polar and do not mix well with H2O B. They have metals that are much denser than water C. They have high charge density which makes stronger ionic bonds that water can’t break D. They have weak ionic bonds that cause them to precipitate E. The higher pressure of water causes solids to precipitate
