Wordpress Nav Active 'selected'

Hi everyone! Pretty new with wordpress and I'm having some issues with a nav bar. Inside the index.page I have a sublink that goes to a new page called News but I stil want HOME to appear active although it stays innactive. Here's the code:

Nav (header.php) <li><a href="<?php bloginfo('url'); ?>/home" class="<?php if(is_page('Home')) {echo 'selected';} ?>">Home</a></li> <li>·</li> <li><a href="<?php bloginfo('url'); ?>/biography" class="<?php if(is_page('Biography')) {echo 'selected';} ?>">Biography</a></li> <li>·</li> <li><a href="<?php bloginfo('url'); ?>/gallery" class="<?php if(is_page('Gallery')) {echo 'selected';} ?>">Gallery</a></li>

Link (index.php) <a href="<?php bloginfo('url'); ?>/home/news" class="<?php if(is_page('Next')) {echo 'selected'} ?>" id="next">Next</a>

I tried to find a way to change 'selected' to 'home' but I haven't managed to find a way. Could someone help me with this problem?

Much appreciated!
