The main secondary structure in <scene name='60/602771/Octamero/2'>histones</scene> is <scene name='60/602771/Secondarystructure/1'>alpha helices</scene>. | The main secondary structure in <scene name='60/602771/Octamero/2'>histones</scene> is <scene name='60/602771/Secondarystructure/1'>alpha helices</scene>. | ||
If we | If we highlight the different types of amino acid residues on the <scene name='60/602771/Esqueleto/1'>protein backbone</scene> we can see that <scene name='60/602771/Residuosnegativos/1'>negatively charged residues</scene> and <scene name='60/602771/Residuospositivos/1'>positively charged residues</scene> are arranged so positively charged residues are in <scene name='60/602771/Periferia/1'>peripheral positions</scene>, where they can form ionic interactions ([[salt bridges]]) with <scene name='60/602771/Interacciones/1'>phosphate groups on the DNA molecule</scene>. This distribution of electric charges stabilizes the whole structure. | ||
