WebPolynucleotides The polymer of nucleotides is called a polynucleotide. Created via condensation reactions between the deoxyribose sugar and the phosphate group, creating a phosphodiester bond. The DNA polymer occurs in pairs joined by hydrogen bonds between bases. This creates the double helix. Hydrogen bonds an only form between … WebThe four nitrogen bases found in DNA are adenine, cytosine, guanine, and thymine. Each of these bases are often abbreviated a single letter: A (adenine), C (cytosine), G (guanine), T (thymine). The bases come in two categories: thymine and cytosine are pyrimidines, while adenine and guanine are purines (). Figure %: DNA Bases
