Question

pMDawn is digested with EcoR1, and BamHI. Resulting in fragments shown below:

EcoRI: 20 kb

BamHI: 11 kb, 6 kb, 3 kb

EcoRI + BamHI: 8 kb, 6 kb, 3 kb

If the BamHI/EcoRI double digest produces only 3 fragments what are their sizes, why is this so?

   

There are two 3 kb fragments

   

There are two 6 kb fragments

   

There are two of the same size fragments, but we don't know which.

   

We cannot determine this from the information given.
