WebThe duplication of DNA is called DNA replication, and it is initiated by complex enzymes called DNA polymerases. These progress along the molecule, reading the sequences of nucleotides that are linked together to make DNA chains. WebMar 15, 2016 · If an error is not corrected and remains present in the new DNA strand then every time that strand of DNA is replicated the error will be replicated. If an error occurs in sperm or egg cells the mutation can be passed to the next generation. Most mutations are harmful but some can be beneficial.
