Replication starts at the ORIGIN OF REPLICATION.
In prokaryotes which has close double stranded DNA molecule, replication usually starts from a single origin of replication and it proceeds around the circle bidirectionally, that is, in both directions. The process of replication in prokaryotes is very rapid and it produces only a few errors.<span />
Polar covalent bonds.

During an enzymatic reaction, a molecule of substrate binds to the enzyme and is broken down into one or more molecules of product , which are released.
<h3>What is substrate and product ?</h3>
While products can be produced at the end of the reaction, substrates are the reaction's initial raw material. The distinction between a substrate and a product is that a substrate is the substance used to initiate a chemical reaction, whereas a product is the compound formed when the reaction is finished.
<h3>What do you mean by enzymatic reaction ?</h3>
In an enzyme reaction, the free enzyme E binds to its substrate S to form the enzyme-substrate complex (C1), which is then catalyzed into the enzyme-product complex (C2), from which the free enzyme and product P are released: S + E ↔ C1 ↔ C2 → P + E. This is known as the "lock-and-key" model in enzymatic reactions. The great majority of cellular reactions are represented by this paradigm.
Thus from the above conclusion we can say that during an enzymatic reaction, a molecule of substrate binds to the enzyme and is broken down into one or more molecules of product , which are released.
