Biological molecules wksht A: Polynucleotide formation

Please note that:

1) The raw material needed is a nucleoside TRIphosphate. But the monomer that is eventually making up the polynucleotide chain (polymer) is a nucleotide (aka nucleoside MONOphosphate).

2) This is NOT a condensation reaction as NO water molecule is evolved. Instead, pyrophosphate is evolved.
