Explanation:
DNA is the stored form of the genetic material in living organisms. DNA is a long chain polynucleotide made up of nucleotide subunits. The nucleotides are monomers that comprises of a five carbon sugar (Deoxyribose), a phosphate group and nitrogenous bases (Adenine, Guanine, Cytosine and Thymine). A DNA molecule has segments that holds the information to build an organism and pass genetic traits to offsprings. This segment is called GENE.
However, before this genetic material can be passed on to an offspring or be used in an organism's growth and development, it needs to divide into the cells that require it. Before it can divide into the cells, it needs to be replicated in order for each cell it is dividing into, to have an equal and correct number.
The DNA is also capable of change in its nucleotide sequence so as to achieve genetic variation.
