Practice questions

An enzyme binds double-stranded DNA by interacting with the major groove, where chemical groups from base pairs are exposed. In a particular 12-bp region, the enzyme recognizes the pattern of hydrogen-bond donors and acceptors presented in the groove. A lab-made duplex has the same base sequence but is synthesized with the complementary strand reversed so that the phosphodiester backbone runs 5'→3' in the same direction as the original strand (parallel rather than antiparallel). The bases are still capable of hydrogen bonding, but the geometry of the grooves changes. Which statement best predicts the consequence for enzyme binding?
