  87. 87. Why DNA Replication Occurs and What are Genetic Mutations DNA Replication occurs in order to form new cells with the same “instructions” to do the same tasks as other cells. For example, if you need more cells to produce energy, then a cell that is already “programmed” to produce energy replicates itself and then you have to cells to produce energy. Genetic mutations occur when the cell is replicating and a nitrogen base is paired with its noncorresponding nitrogen base such as A-G or C-T. Examples of genetic mutations that occur are most types of cancers, Lou Gehrig's disease, and stopping growing at an extremely young age. Some genetic mutations are very common and happen regularly and they have no major affect on us. Others are very rare and can kill you.
