WebOct 2, 2024 · Mutations occur when mistakes occur in DNA duplication. All cells need to divide and this can only occur when the DNA sequence is replicated into the new cell. Since all DNA is double-stranded, then cell division starts by the separation of the two strands. A DNA polymerase will copy the sequences and thus create two separate DNA molecules.
