WebThe conjugate acids of the adenine and guanine have pK a 's between 9-10. Guanine also has a nitrogen with a pK a of 12.3, which would be mostly protonated at pH 12. The pK a for the phosphoric acid proton of a nucleotide is significantly lower than 7.. Therefore, in a pH 8 buffer, the basic nitrogens of each adenine and guanine are protonated, while the … WebRNA, abbreviation of ribonucleic acid, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA (deoxyribonucleic acid) as a carrier of genetic codes in some viruses. RNA consists of ribose nucleotides (nitrogenous bases appended to a ribose sugar) attached by phosphodiester bonds, forming strands of …
