DNA molecules can be tens of thousands of base pairs in length. Mistakes in DNA replication lead to mutations, which may or may not be harmful to an organism.

Step 1I'll solve this problem step by step, focusing on the mechanism of semi-conservative DNA replication and its role in minimizing mutations.
Step 2: Understand Semi-Conservative Replication
DNA_{parent} \rightarrow DNA_{parent} + DNA_{new}
Semi-conservative replication is a fundamental process where each new DNA double helix contains one original (parent) strand and one newly synthesized (daughter) strand.
Final Answer
Semi-conservative replication minimizes mutations by using each parent DNA strand as an exact template for new strand synthesis, with built-in error-checking mechanisms that ensure high-fidelity genetic information transfer.
