The <span> Nitrogenous bases </span><span> of dna form the rungs, linking the Nucleotides strands together through P</span>hosphodiester bonds . Each rung<span> is made up of two bases that </span>link together and because of their chemical nature, A (<span>adenine ) </span><span>will only </span>link with T (thymine) and G (<span>guanine ) </span><span> will only </span>link with C (<span>cytosine)</span><span>. </span>Nucleotides are joined together<span> to </span>form<span> two long </span>strands <span>that spiral to build a structure called a double helix. If it looks like a ladder, the phosphate and sugar molecules would be the </span>sides<span>, while the bases would be the </span>rungs.
