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).

2023年7月29日 · Three main types of RNA are involved in protein synthesis. They are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). mRNA is transcribed from DNA and contains the genetic blueprint to make proteins. Prokaryotic mRNA does not need to be processed and can proceed to synthesize proteins immediately.

2024年4月21日 · RNA molecules perform a variety of roles in the cell but are mainly involved in the process of protein synthesis (translation) and its regulation. RNA is typically single stranded and is made of ribonucleotides that are linked by phosphodiester bonds.
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.

The rRNA is mainly composed of cellular RNA and are the most predominant RNA within the cells of all living beings. mRNA – Messenger RNA. This type of RNA functions by transferring the genetic material into the ribosomes and pass the instructions about the type of proteins, required by the body cells.
