B
Solution:
Phosphate groups are attached to the 5'- and 3'-carbon atoms of each sugar to form the backbone chain of DNA. One end of the chain carries a free phosphate group attached to the 5'-carbon atom; this is called the 5' end of the molecule. The other end has a free hydroxyl (-OH) group at the 3'-carbon and is called the 3' end of the molecule.
