The DNA Restriction Mapping Model simulates the cutting of a DNA molecule at each occurrence of the sequence GTGCAC or GTTAAC, turning the DNA strand into several smaller strands. These fragments can then be pieced together to create a map of the original DNA molecule, a process that is called Restriction Mapping. This model takes a set of DNA fragment lengths as input and returns all possible combinations that could produce the original DNA strand.  To visualize the DNA molecule, the simulation draws a reconstruction using a different color to mark each fragment.  It is possible for this reconstruction to have several solutions, or to have no solution at all. 

The DNA Restriction Mapping Model is distributed as a ready-to-run (compiled) Java archive.   Double clicking the jar file will run the program if Java is installed.  You can modify this simulation if you have EJS installed by right-clicking within the map and selecting "Open Ejs Model" from the pop-up menu item.
