Extension Process
Definition
The extension process in DNA replication is the phase where new DNA strands are synthesized by adding nucleotides to the primer, which is complementary to the template strand.
Analogy
Think of it like building a Lego tower. The primer acts as your base or foundation and each nucleotide added during the extension process is like an additional Lego block being stacked on top of that base.
