Explain the two reasons why DNA changes

1.) Mutation or outside effect

2.) The DNA copies itself

Explanation:

1.) Mutations can occur when a body is exposed to high amounts of radiation or other harmful chemicals, thus changing the DNA.

2.) In order for our bodies to grow, cells must divide and make new cells. Each time a cell makes new cells, the DNA has to copy itself for the new cell. This process is called “replication.”
