Each living cell has two different types of nucleic acids. One of them is called Deoxyribonucleic Acid (DNA) and the other is called Ribonucleic Acid (RNA).

Deoxyribonucleic Acid (DNA) is primarily found in the nucleus of living cells. It contains the genetic code to make Ribonucleic Acid (RNA). Ribonucleic Acid (RNA) on the other hand is found in the cytoplasm and has the genetic codes responsible to allow it to dictate the primary sequence for the formation of proteins.

Looking at the structural differences between the two, DNA is a nucleic acid that has the pentose sugar deoxyribose while RNA has the pentose sugar ribose. Both DNA and RNA have the three heterocyclic amines, adenine, guanine, and cytosine but they differ in the fourth. DNA has thymine while in RNA it is replaced with uracil
