During DNA replication, if an error is made and not caught by DNA polymerase, only the newly synthesized daughter strand will contain the mutation. The original (template) strand remains unchanged. DNA polymerase has proofreading capabilities, but errors can occasionally slip through, leading to mutations in the daughter strand.
