Answer: Genes are responsible for coding proteins, which are needed for all of our body functions and to build our body structures. So, a mutation could affect the way a protein is made. If the error occurs in the gamete cell, it could lead to a mutation in a growing fetus. Because all cells in the body form from two fertilized gametes, this mutation may exist in all the cells of the developing baby. If it occurs in another cell, a skin cell, for example, then the mutation would be confined to the cells in the skin tone.

As DNA replication begins the DNA molecule is broken apart into two complementary strands. DNA replication is the process by which DNA makes a copy of itself during cell division. The process occurs in all living and is the basis for biological inheritance. The process starts with the separation of DNA strands in the double helix. Then replication for is formed followed by the binding of bases to each strand. Then the last step is termination of the Replication process
