RNA: Properties, Structure, Composition, Types, Functions
2023年8月3日 · The three-dimensional structure of RNA is critical to its stability and function. RNA being a single-stranded molecule can form a complex structure by allowing its ribose sugars and bases to be modified on the action of cellular enzymes (that attach chemical groups), to perform different functions.

2024年12月28日 · 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.
RNA - Wikipedia
The chemical structure of RNA is very similar to that of DNA, but differs in three primary ways: Unlike double-stranded DNA, RNA is usually a single-stranded molecule (ssRNA) [4] in many of its biological roles and consists of much shorter chains of nucleotides. [5]

2023年7月29日 · What is the composition of RNA? The primary structure of RNA is composed of nucleotides attached by 5’-3’ phosphodiester bonds between ribose sugars. Ribose has the molecular formula C5H10O5 and has a naturally occurring D-ribose form and a less common L-ribose. The D and L designations refer to the hydroxyl group positions.
1.2: Structure of DNA and RNA - Biology LibreTexts
DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are composed of two different classes of nitrogen-containing bases: the purines and pyrimidines. The most commonly occurring purines in DNA are adenine and guanine: The most commonly occurring …

2023年9月29日 · RNA is a single stranded, helical structured complex amino acid that serves as genetic material for prokaryotes and almost all viruses. In this article you can find complete details on RNA.
8.2: Nucleic Acids - RNA Structure and Function
RNA: Structure and Function. Ribonucleic acids are very similar in chemical structure to DNA except they contain ribose instead of deoxyribose. They also have the pyrimidine base uracil instead of thymine, as shown in Figures 1 and 2 above.
