PLEASE NOTE. Chime has been discontinued but you can still get copies - see below. These pages and the DNA tutorial may be removed soon due to the Chime plug-in being discontinued.

To use tutorial you need to install a plugin called "Chime".

Go to http://www.umass.edu/microbio/chime/neccsoft.htm#download_install, and then download the "Chime" installer.

If you are using a Macintosh computer you will need to use Netscape Navigator. Both Netscape and Internet explorer work on the PC.
