DNA is replicated whenever a cell needs to divide. This happens at many times during an organism's lifetime. All cells are replicating during embryo development and most are still replicating during a juvenile period of growth. In adults, some tissues need to grow continuously. In humans for example, skin and epithelial cells that line the intestinal tract are constantly being shed and replaced. Other cells only grow when there is damage to be repaired. A few cell types such as neurons, stop replicating in adults forever as far as we know (although there are a few hints that this may not be completely true).
