Hybridization simply means that DNA will re-nature and form a stable double helix only with its particular match, only with the hybrid that it is perfectly complementary, too.

核酸分子杂交表示,DNA在变性状态下可以恢复活性,和与其配对的单链形成稳定的双螺旋结构,只有在完全配对时才会发生这种情况

DNA. This molecule is a double-stranded helix made from four different types of sub-molecule.

ECONOMIST: Genetics gets more complicated

Obviously weather has, over the past several days, complicated our efforts to introduce additional containment vessels -- the Helix is a device that was -- its date has been pushed back in terms of additional containment capacity, as the Enterprise and the Q4000 continue to average above 20, 000 barrels of oil a day accumulating in from the leaking well.
