The
covalent bond that attaches a
phosphate group to a
molecule by way of an
oxygen atom (which, out of two possible bonds, is bonded to the phosphate group on one side and the rest of the molecule on the other). This is the type of
bond that links the
nucleotide subunits together to make a
DNA or
RNA molecule.
