The reason why it is advantageous to have weak hydrogen bonds between complementary base pairs and strong covalent bonds between phoshate and deoxyribose groups in a DNA molecâ¦ule is because the strong covalent bonds running along the  ladder  of the DNA molecule ( the phospate and deoxyribose units ) keep the molecule together during its ...
The type of chemical bonds that hold the parts of each nucleotide  together is a hydrogen bond. It connects each nitrogenous base of  nucleotide in DNA and RNA.ovalent bonding holds CuCl2 together. Covalent bonding is a shared electron pairing of electrons from a non-metal and a metal. For the sake of your chemistry professor's sani â¦ ty please memorize the metals and nonmetals on the periodic table. In fact just memeorize the periodic table.
