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.

Translation is the second part of the central dogma of molecular biology: RNA → Protein. It is the process in which the genetic code in mRNA is read, one codon at a time, to make a protein. Figure below shows how this happens.

2024年5月24日 · 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.

The main role of the ribosomal proteins seems to be to stabilize the RNA core, while permitting the changes in rRNA conformation that are necessary for this RNA to catalyze efficient protein synthesis.

In the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred...

RNA binding proteins (RBPs) comprise a large class of over 2000 proteins that interact with transcripts in all manner of RNA-driven processes. The structures and mechanisms that RBPs use to bind and regulate RNA are incredibly diverse.

2019年2月25日 · Recent progress has expanded the number of methods for studying RNA–protein interactions in two general categories: approaches that characterize proteins bound to an RNA of interest...

The central dogma of life can be defined in a fairly simple way: DNA makes RNA, which in turn makes proteins: In transcription, your genetic code is transcribed, or written, into RNA. In translation, this RNA is then translated into proteins.

2 天之前 · 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.

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.
