Question

When a cell divides to make two new cells, it copies its DNA first. This is called DNA replication. Why do you think this is important when making body cells like skin or muscle or bone?

Answer 1

DNA replication is important because without it, cell division could not occur. With DNA replication, the set of DNA of a cell can be duplicated and then each cell that results from division can have its own entire set of DNA, and cell division can theoretically continue indefinitely.
