RNA: Properties, Structure, Composition, Types, Functions
2023年8月3日 · 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).
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.

RNA has the same nitrogen bases called the adenine, Guanine, Cytosine as that of the DNA except for the Thymine which is replaced by the uracil. Adenine and uracil are considered as the major building blocks of RNA and both of them form base-pair with the help of 2 hydrogen bonds.
