<p>specific base pairing patterns that identify particular regulatory regions of genes.<a href="page.php?w=Hydrogen_bond">Hydrogen bond</a>ing is the chemical mechanism that underlies the base-pairing rules described above. Appropriate geometrical correspondence of hydrogen bond donors and acceptors allows only the "right" pairs to form stably. DNA with high GC-content is more stable than DNA with low <a href="page.php?w=GC-content">GC-content</a>, but contrary to popular belief, the hydrogen bonds do not stabilize the DNA significantly and stabilization</p><p>
