Define DNA copying. State its importance.

DNA copying: DNA copying is also known as DNA replication, it is the biological process of creating two identical copies of DNA from a single original DNA molecule. 

Importance of DNA copying: 

1. It makes sure that each daughter cell produced at the end of cell division receives an identical amount of DNA. 
2. It generates variation during sexual reproduction which leads to evolution. 
3. It aids the transmission of information from parents to children.  
4. DNA is necessary to make all the RNA and proteins needed for cells to out necessary reactions.
