Hy-Vee produce gets ugly; Stores debuts Misfits program to sell imperfect fruits and vegetables at a lower cost to help reduce food waste. WEST DES MOINES â To combat the nationâs food waste issue, Hy-Vee Inc. recently began offering so-called âuglyâ produce in nearly all of its 242 grocery stores.
In other words, DNA polymerase is an enzyme that synthesizes a product by interpreting the existing DNA strand as a template and produces the complementary sequence of the template into a new strand. 3. DNA polymerases necessitate the presence of a primer to start synthesis.The reaction catalyzed by DNA polymerases that works to elongate the chain is a nucleophilic attack by the 3âOH terminus of the growing chain on the innermost phosphorus atom of the deoxynucleotide triphosphate.Therefore, a primer strand with a free 3'-OH group must be bound to the template strand from the start.he reaction catalyzed by DNA polymerases that works to elongate the chain is a nucleophilic attack by the 3âOH terminus of the growing chain on the innermost phosphorus atom of the deoxynucleotide triphosphate.

In addition to these proteins, several other enzymes are involved in bacterial DNA replication. 1  DNA Polymerase-DNA Polymerase I (Pol I) was the first enzyme discovered with polymerase activity, and it is the best characterized enzyme. 2  5' to 3' elongation (polymerase activity). 3  3' to 5' exonuclease (proof-reading activity). 4  5' to 3' exonuclease ....n addition to these proteins, several other enzymes are involved in bacterial DNA replication.
