DNA vs. RNA — What's the Difference?
By Tayyaba Rehman — Updated on September 21, 2023
DNA contains genetic instructions for organisms, with a double helix structure; RNA transfers genetic information and is typically single-stranded.

Key Differences
DNA, or Deoxyribonucleic acid, is the molecule that carries the genetic code for all living organisms. RNA, or Ribonucleic acid, on the other hand, acts primarily to transfer the genetic information contained within DNA to the cellular machinery that produces proteins.
DNA possesses a stable, double-helix structure, forming a twisted ladder-like shape. RNA is usually single-stranded and can assume various shapes, giving it versatility in its function and role in protein synthesis.
DNA resides mainly in the cell nucleus in eukaryotic organisms. RNA, once synthesized using DNA as a template, often travels out of the nucleus into the cell's cytoplasm, where it plays its part in the process of protein synthesis.
The building blocks of DNA include four bases: adenine, thymine, cytosine, and guanine. In RNA, thymine is replaced by uracil, making the four bases adenine, uracil, cytosine, and guanine.
To sum up, while DNA acts as the long-term storage for genetic information, RNA serves as the messenger that carries this information to where it's needed for the creation of proteins and other functions.

RRNA and tRNA are essential types of RNA for protein assembly.
Dna
Deoxyribonucleic acid, a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
Rna
Ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.
Dna
A nucleic acid that carries the genetic information in cells and some viruses, consisting of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. DNA sequences are replicated by the cell prior to cell division and may include genes, intergenic spacers, and regions that bind to regulatory proteins.
Rna
A nucleic acid present in all living cells and many viruses, consisting of a long, usually single-stranded chain of alternating phosphate and ribose units, with one of the bases adenine, guanine, cytosine, or uracil bonded to each ribose molecule. RNA molecules are involved in protein synthesis and sometimes in the transmission of genetic information. Also called ribonucleic acid.
Dna
Alternative form of DNA
Rna
(biochemistry) a long linear polymer of nucleotides found in the nucleus but mainly in the cytoplasm of a cell where it is associated with microsomes; it transmits genetic information from DNA to the cytoplasm and controls certain chemical processes in the cell;
Ribonucleic acid is the genetic material of some viruses
Dna
Abbreviation for deoxyribonucleic acid; - more commonly used than the full name. See also RNA.
Dna
(biochemistry) a long linear polymer found in the nucleus of a cell and formed from nucleotides and shaped like a double helix; associated with the transmission of genetic information;
DNA is the king of molecules
