Ligation and Recleavage:

• After 50-fold overdigestion with DraI, more than 95% of the DNA fragments can be ligated and recut

Methylation Effects:

• Dam: never overlaps — no effect
• Dcm: never overlaps — no effect
• CpG: never overlaps — no effect
• EcoKI: may overlap — blocked
• EcoBI: never overlaps — no effect

Digestion of Agarose-embedded DNA:

• Minimum 5units of the enzyme are required for complete digestion of 1μg of agarose-embedded lambda DNA in 16hours
