The nucleotides of a single strand of DNA are held together
     The nucleotides of a single strand of DNA are held together by Select one: a. covalent bonds between nitrogenous bases b. covalent bonds between sugars and nitrogenous bases c. hydrogen bonds between sugars and phosphate d. hydrogen bonds between nitrogenous bases e. covalent bonds between sugars and phosphates  
  
  Solution
e. Covalent bonds between sugars and phosphates.
Because a single strand of DNA is made of sugar and phosphate backbone that looks like a ribbon , in a double helix model of DNA.
