RNA - Wikipedia
Ribonucleic acid (RNA) is a polymeric molecule that is essential for most biological functions, either by performing the function itself (non-coding RNA) or by forming a template for the production of proteins (messenger RNA). RNA and deoxyribonucleic acid (DNA) are nucleic acids.
Ribonucleic Acid (RNA) - National Human Genome Research Institute
Ribonucleic acid, or RNA. I often think of RNA as being the less well-known cousin of DNA, particularly for people outside the field of biology or genomics. But really, when you think about it, RNA, in so many ways, is the actual functional form of nucleic acids that really the body uses to do the business of, you know, constructing cells or responding to immune challenges, of carrying amino ...
What Is Ribonucleic Acid? - Sciencing
Ribonucleic acid, or RNA, is one of the two types of nucleic acids found in life on Earth. The other, deoxyribonucleic acid (DNA), has long assumed a higher profile than RNA in popular culture, in the minds of casual observers and elsewhere. RNA, however, is the more versatile nucleic acid; it takes the instructions it receives from DNA and transforms them into a variety of coordinated ...
Ribonucleic Acid (RNA) Fact Sheet
Ribonucleic acid (RNA) is an essential molecule that performs many roles in the cell, from carrying the instructions to make proteins to regulating genes.
RIBONUCLEIC ACID Definition & Meaning - Merriam-Webster
The meaning of RIBONUCLEIC ACID is rna. But mRNA vaccines use a piece of mRNA, or messenger ribonucleic acid, that encodes for a viral protein. Elise Haulund, CNN Money, 14 Aug. 2026 An mRNA vaccine, or messenger ribonucleic acid vaccine, is a type of immunization that uses a copy of a molecule called messenger RNA to help the body create an effective immune response. Mary Walrath-Holdridge ...

Explore the vital role of Ribonucleic acids in biology. Learn about RNA structure, key types like mRNA and tRNA, and their impact on protein synthesis.
RNA | Definition, Structure, Types, & Functions | Britannica
RNA, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA as a carrier of genetic codes in some viruses. RNA consists of ribose nucleotides and the nitrogenous bases adenine, guanine, cytosine, and uracil. Learn about the structure, types, and functions of RNA.
Messenger RNA - Wikipedia
Messenger ribonucleic acid (mRNA) is a single-stranded molecule of RNA that corresponds to the genetic sequence of a gene, and is read by a ribosome in the process of synthesizing a protein. [1][2]
RNA - Simple English Wikipedia, the free encyclopedia
RNA is an acronym for ribonucleic acid, a nucleic acid. Many different kinds are now known. [1] RNA is physically different from DNA. DNA has two strands that twist around each other, but RNA only has one strand. RNA also has different bases than DNA. These bases are adenine, guanine, cytosine, and uracil. Adenine bonds with uracil.
What Is RNA? RNA Facts - Science Notes and Projects
Ribonucleic acid or RNA is a nucleic acid found in all living cells. While RNA resembles DNA in many ways, it contains a different set of bases, usually is single-stranded instead of double-stranded, and transcribes DNA so a cell can make proteins. Like DNA, RNA molecules consist of a backbone of alternating phosphate and sugar groups.
