DNA strands are split apart to allow an opening for replication. The
opening has two replication forks so synthesis goes toward them in 5' to
3' direction.

Enzymes are highly specific proteins that function best at certain pHs. A change in pH would affect its structure; too high or too low would cause denaturation. When this happens, the enzyme won’t have the correct structure to function as a catalyst. Therefore, reaction rate will slow.
