Ribonucleic Acid (RNA) - National Human Genome Research Institute
Ribonucleic acid (abbreviated RNA) is a nucleic acid present in all living cells that has structural similarities to DNA. Unlike DNA, however, RNA is most often single-stranded. An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA.

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) Fact Sheet - National Human Genome Research ...
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, shortened to RNA, is one of the most versatile molecules of life.

RNA | Definition, Structure, Types, & Functions | Britannica
RNA, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA (deoxyribonucleic acid) as a carrier of genetic codes in some viruses. RNA consists of ribose nucleotides (nitrogenous bases appended to a ribose sugar) attached by phosphodiester bonds, forming strands of varying lengths.

What Is Ribonucleic Acid? - Sciencing
Ribonucleic acid, also known as RNA, is one of the two major nucleic acids in the body. The other major nucleic acid is deoxyribonucleic acid, or DNA, which carries the genetic code of the cell. Together, these two molecules direct every activity in the body.

What is RNA? Exploring the Role and Importance of Ribonucleic Acid in Life
RNA, or ribonucleic acid, is a fascinating molecule that plays a crucial role in the machinery of life. It is often described as the messenger that bridges the gap between the genetic information encoded in DNA and the proteins that form the structure and function of living organisms.

RNA: Properties, Structure, Composition, Types, Functions
RNA (Ribonucleic acid) is a single-stranded nucleic acid molecule and made up of ribonucleotides. A ribose nucleotide in the chain of RNA consists of a ribose sugar, phosphate group, and a base. In each ribose sugar, one of the four bases is added: Adenine (A), Guanine (G), Cytosine (C), and Uracil (U).

The 3 Types of RNA and Their Functions - ThoughtCo
There are several types of ribonucleic acid, or RNA, but most RNA falls into one of three categories. mRNA transcribes the genetic code from DNA into a form that can be read and used to make proteins. mRNA carries genetic information from the nucleus to the cytoplasm of a cell.

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.

RNA (Ribonucleic Acid): Definition, Function, Structure
Ribonucleic acid (RNA) is one of two forms of genetic information in the cell. RNA works together with _ deoxyribonucleic acid _ (DNA) to help express genes, but RNA has a distinct structure and set of functions within the cell.
