Question: A double-stranded piece of DNA, 100 base pairs in size, is exposed to a high pH environment. This causes all non-valent interactions to be disrupted. Determine what will result from this treatment?
a) 200 nitro bases, 200 phosphates and 200 sugars,
b) Two 100 single-stranded DNA molecules
c) 100 individual base pairs, but no longer one molecule
d) 200 individual nucleoside monophospates
e) The molecule will remain unchanged (it will still be double-stranded, 100 base pairs)
