... HELICAL Earlier we emphasized that polymeric molecules , like proteins and nucleic acids , have regular linear backbones in which specific groups ( e.g. , —CO – NH– ) repeat over and over along the molecule . Often these regular groups ...

... helical rotation would have to vary with the sequence of bases . The presence of complementary base pairs in double - helical DNA makes a regular structure possible , since each base pair is of the same size . DNA MOLECULES ARE STABLE ...
