What is the role of his 12 in the RNase-catalyzed hydrolysis of RNA, as indicated in the Figure below? 5' His 119 RNA CH₂ H H 3 O Base 1' 12' 8-H His 12 -P-0-CH₂ a Base H H O -0-P=O H OH NH It acts as a general base, abstracting a proton from the 2' hydroxyl in order to increase its nucleophilicity. It forms an H-bond with his119 in order to stabilize the transition state. It donates a proton to improve the quality of the leaving group. It works through concerted general acid-base catalysis with his119 in order to favour the products of the reaction. Two of the above are true.
The hydrophobic effect explains why: O Water regulates pH in the interstitial fluid between eukaryotic cells. O Salt bridges form between oppositely charged histones and DNA in an aqueous environment. Nitrogenous bases are in the interior of the helix, when DNA is in an aqueous environment. Oil forms a homogenous mixture with polar solvents, like acetone.
