Restriction sites

In a restriction mapping experiment using the plasmid P (ST), you cleave the circular plasmid with the restriction enzymes Xbal, Asp718, BamHI and EcoRI individually and in various combinations with each other. You obtain DNA fragments with the following sizes:

Enzymes used            size of DNA fragments (bp)

BamHI, EcoRI, Xbal         3000, 1550
Asp718, BamHI, Xbal       3000, 2500, 600
Asp718, BamHI               5500, 600
Asp718, Xbal                   3600, 2500
BamHI, Xbal                    3100, 3000
Asp718                           6100
BamHI                            6100
Xbal                               6100

Using the data above, make a map of the P (ST) plasmid indicating the distances between each restriction site for each of the four enzymes.
