1a) How many EcoRI recognition sites are in the DNA molecule?
1, 2, 3 or 4?
1b) do the sizes of the DNA fragments from the BamHI digest add up to the same as those of the EcoRI digest?
a) Yes, because the enzymes do the same job: to cut the DNA.
b) Yes, because the same DNA molecule was used in the digests.
c) No, because the fragment sizes produced by the two enzymes are different.
d) No, because the enzymes have different cutting sites.
