A DNA template plus primer with the structure (where =a phosphate group ) is placed in an in vitro DNA synthesis system containing `Mg^(2+)` , an excess of the four deoxyribonucleoside triphosphates, etc. and a mutant form of E. coli DNA polymerase I that lacks `5'rarr 3'` exonuclease activity . The `5' rarr 3'` polymerase and `3' rarr 5'` exonuclease activities of this aberrant enzyme are identical to this aberrant enzyme are identical to those of normal E. coli DNA polymerase I. It simply has no `5'rarr 3'` exonuclease activity . What will be the structure of the final product ?
