·      DNA (Deoxyribonucleic Acid) and RNA (Ribonucleic Acid) are two different nucleic acids found in the cells of every living organism. Both have significant roles to play in cell biology.

·      DNA is found mainly in the nucleus of the cell, while RNA is found mainly in the cytoplasm of the cell.

·      DNA contains the genetic codes to make RNA and the RNA in turn then contains the codes for the primary sequence of amino acids to make proteins.

·      Within the cell structure, DNA is organized into structures called chromosomes, which are duplicated during cell division. These chromosomes would then release the genetic codes that will be transcribed and carried by the RNA to the ribosome. The ribosome will then synthesize new proteins that will help the body grow.

·      DNA and RNA contains same nucleotide namely Adenine, Guanine and Cytosine but they differ with respect to DNA contains thymine whereas RNA contains Uracil.
