DNA Artist

From Kangaroo Molbio Software:

DNA Artist is a collection of small Molecular Biology programs. You can do things like search for Compatible Enzyme ends or do a PCR Melting point temperature calculation with different formulas, or you can run a Digest Preview of an Agarose Gel etc.

DNA Artist is an Internet Application, which means it works like an Internet browser (e.g. Netscape Navigator or Internet Explorer).

The Application Navigator is the central access point of DNA Artist,it connects to the Internet and downloads small files, which are interpreted from the application and compiled into a form that you can actually use these modules as individual programs.
