bond
the linkage between atoms or radicals of a chemical compound, or the symbol representing this linkage and indicating the number and attachment of the valencies of an atom in constitutional formulas, e.g. H−O−H, H−C= C−H and can be represented by a pair of dots between atoms, e.g. H:O:H, H:C:::C:H.

Answer 2

I figured out it is a condensation reaction after all: http://www.bio.miami.edu/dana/pix/phosphodiester.jpg

I appreciate your help though.
