WebWhat's the pKa of the phosphate group in DNA and RNA molecules? Phosphoric acid, when free in solution, is a triprotic acid with pKa1 = 2.2, pKa2 = 7.2, and pKa3 = 12.4. But most … WebDNA is a nucleic acid, one of the four major groups of biological macromolecules. Nucleotides All nucleic acids are made up of nucleotides. In DNA, each nucleotide is made up of three parts: a 5-carbon sugar called deoxyribose, a phosphate group, and a nitrogenous base.

WebSep 9, 2024 · Phosphate Groups in Nucleic Acids. Nucleic acids, like DNA, are made of nucleotides.Where do phosphates come in? Well, nucleotides include a base, a sugar, and one or more phosphates. Webof one phosphate group, one sugar ring, and one nitrogen-containing base. • DNA has 4 types of bases: Adenine, Thymine, Cytosine, and Guanine (A, T, C, and G). These bases have strict binding rules, as A only bonds with T (and vice versa), and C only bonds with G. This is important for DNA replication to work. hillingdon post office opening times
