Newly formed DNA copies may not be identical at times. Give one reason.

Explanation

**Step-by-Step Solution:**

1. **Understanding DNA Replication**: DNA replication is the process by which a cell makes an exact copy of its DNA before cell division. This involves unwinding the double helix structure and synthesizing new strands complementary to the original strands.

2. **Errors During Replication**: During the synthesis of new DNA strands, there can be mistakes or errors. These errors can occur due to various factors such as environmental influences, chemical reactions, or simply the inherent limitations of the DNA polymerase enzyme that synthesizes the new strand.

3. **Inaccuracy in Copies**: Because of these errors, the newly formed DNA strands may not be perfect copies of the original DNA. This can lead to variations, which means that the copies may differ from each other.
