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. how does semi-conservative replication help prevent mutations during dna replication
The answer is "Half of the strand is already correct and does not need correction".
Semiconservative replication would create two duplicates that each contained one of the first strands and one new strand. Moderate replication would leave the two unique format DNA strands together in a twofold helix and would create a duplicate made out of two new strands containing the greater part of the new DNA base sets.
