WebA final LiCl concentration of 2-3 M is needed to precipitate RNA (adding an equal volume of 4 M LiCl, 20 mM Tris-HCl, pH 7.4, and 10 mM EDTA works well). Note that no alcohol is needed for LiCl precipitation. RNA should be allowed to precipitate at -20°C; precipitation time depends on RNA concentration. WebAs new nucleotides are added to a strand of DNA or RNA, the strand grows at its 3’ end, with the 5′ phosphate of an incoming nucleotide attaching to the hydroxyl group at the 3’ end of the chain. This makes a chain with each sugar joined to its neighbors by a set of bonds called a phosphodiester linkage. Properties of DNA
