<h3><b>DNA Polarity</b></h3>
<p> Recall that DNA strands have a 3’ end and a 5’ end and that new nucleotides are added to the free -OH group of the 3’ end. </p>
<br />
<h3><b>Base Pairing</b></h3>
<p>For <b>DNA</b>, there are 4 nucleotide bases: Guanine (G), Cytosine (C), Adenine (A), and Thymine (T). <br /> G pairs with C between complimentary strands via the formation of 3 hydrogen bonds. <br /> Similarly, A pairs with T via the formation of 2 hydrogen bonds. </p>
<br />
<p> For <b>RNA</b>, the bases are the same, except Uracil (U) is used instead of Thymine.<br /> In RNA, A pairs with U, and they form 2 hydrogen bonds. <br /> <em> (Therefore, the RNA bases are: G, C, A, U.) </em> </p>
