Differences Between DNA and RNA

Spread the Differences

There are two types of Nuclei acids in living organism. They are DNA and RNA. DNA refers to Deoxyribonucleic acid and RNA refers to Ribonucleic acids. DNA and RNA plays a major role in the living organisms like transferring genetic data, building proteins which are essential for all the organisms.


DNA is mainly found in the nucleus and it also occurs in the chloroplasts and mitochondria. It is genetic material and contains all the information needed for the existence and development of an organism. It is located by means of Feulgen staining technique which is specific for DNA.

        Watson and Crick are the people who were able to coordinate all the known facts of DNA into a model and proposed a right handed double helix model. DNA consist of 2 poly nucleotide strands which are coiled helically in clock wise direction. DNA is linear polymer. The DNA molecule is the most unique molecule in the living world. It is the only molecule that can replicate itself.


It is found in all living cells. RNA is mostly synthesized in the Nucleus but later it moves into the cytoplasm. RNA is single stranded which consists of only one poly nucleotide strand.

         There are three types of RNA. Ribosomes RNA or R RNA found in the Ribosomes where protein synthesis occurs,. Messenger RNA which is produced in the nucleus and carries information for the synthesis of the proteins. Transfer RNA which collects Amino acids for the cytoplasm for protein synthesis.

Difference between DNA and RNA

Difference between DNA and RNA:

DNA is found in the nucleus of the cell RNA is in the cytoplasm.
DNA has two Deoxy Ribose RNA has Ribose
DNA helps in transferring genetic information RNA helps in carrying the information helps for the Protein building process from Nucleus to Ribosomes
DNA is self replicated which means it can replicate itself when necessary RNA can be self replicated but it can be synthesized from the DNA when it is required
DNA has base pairing with Thymine RNA its base pairing is with the uracil.


In simple terms to differentiate between DNA and RNA, DNA is useful in transferring genetic information useful for the organism and it can replicate itself whereas RNA carries out the information for the synthesis of the protein building and it is synthesized when it is required from DNA.
