It was found , that in the Hyp * . Cyt * , Hyp . Thy * , Hyp . Hyp and Hyp * . Hyp * base pairs all H - bonds are significantly cooperative and mutually reinforce each other , while the C2H ... O2 H - bond in the Hyp . Cyt base pair and the O6H ... O4 H - bond in the Hyp * . Thy base pair behave anti - cooperatively , i . e . , they become weakened , while two others become strengthened .
