DNA Melting - About

stitchprofiles.uio.no

Welcome to stitchprofiles.uio.no

This server performs web-based computations on DNA melting, thus predicting the localized separation of the two strands for sequences provided by the users.

The primary tool here is the stitch profile - a diagram representing the alternative conformations that partly melted DNA can adopt. This new type of diagram is an alternative to the ordinary probability profiles for describing the conformations and their statistics at a given temperature.

In addition to stitch profile diagrams, the server can also plot the usual melting profiles such as melting curves, probability profiles, and temperature profiles.
