Most nurses shudder if they are asked a question about acids, bases or buffers and one can hardly blame them. Much of the complex terminology was devised many years ago and is now out of date. This chapter attempts to correct the situation by giving a simple modern account of the subject...
1、Double strands of DNA are unwound and unzipped and the antisense strand is used as the template. 2、RNA nucleotides pair up with their complementary bases on the template strand via hydrogen bonds. 3、RNA polymerase catalyse the formation of the phosphodiester bonds between the RNAnucleotides. ...
This chapter introduces basic concepts of the properties of water, acids, bases, and buffers. Water plays a major role in all aspects of metabolism: absorption, transport, digestion, and excretion of inorganic and organic substances, as well as maintenance of body temperature. The unique ...
Buffers Although I've told you that acids and bases aren't hard to understand, I've got bad news: There are not one but three common definitions used to describe acids and bases: Arrhenius acids and bases, Brnsted-Lowry acids and bases, and Lewis acids and bases. Though this makes it...
