What are two examples of typos that happen when DNA is being copied?

While most DNA replicates with fairly high fidelity, mistakes do happen, with polymerase enzymes sometimes inserting the wrong nucleotide or too many or too few nucleotides into a sequence. ... But some replication errors make it past these mechanisms, thus becoming permanent mutations.

Explanation:

Any time DNA is copied, a mistake or change can occur in the letters of the DNA sequence, or gene. These changes result in variations or differences in DNA from person to person.
