Answer:
DNA replication produces DNA that will be passed on to the next generation
Step-by-step explanation:
If there is an error in protein synthesis (translation) then that individual protein might be faulty. It might not be able to carry out its function properly, and could be destroyed by the cell. However, this is unlikely to affect the cell long-term, or affect future generations.
In contrast, DNA replication produces the genetic material for the next generation of cells (either diploid daughter cells or gametes). If this has errors, it means that all the cells that come from that cell will contain the error. This also means gene expression at all layers is altered. Therefore, the error has much larger consequences if it is present in DNA replication rather than later stages of gene expression, where mistakes are not permanent
