1. In the DNA Double Helix, complementary base pairs are held together by :   hydrogen bonds   ionic bonds   peptide bonds   N-glycosidic bonds   Hint Half-n-half Clue   2. A significant difference between prokaryotes and eukaryotes is :   Prokaryotes do not have DNA as their genetic material while eukaryotes do.   Prokaryote cells are not membrane-bound while eukaryote cells are.   The DNA of prokaryotes floats freely around the cell while the DNA of eukaryotes is held within its nucleus.   Prokaryotes do not have ribosomes while eukaryotes do.   Half-n-half Clue   3.
