Ribonucleic acid (RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes.RNA and deoxyribonucleic acid are nucleic acids.Along with lipids, proteins, and carbohydrates, nucleic acids constitute one of the four major macromolecules essential for all known forms of life.Like DNA, RNA is assembled as a chain …

rna依存性rnaポリメラーゼ (rdrp) はrnaのゲノムを保有し、かつ増殖ステップにdnaが関わらないウイルスにおいて必須のタンパク質である 。この酵素は鋳型のrnaと相補的となるrnaの合成を触媒する。 rnaの複製機構は2段階からなる。

Religion Newswriters Association - een Amerikaanse organisatie die zich bezighoudt met religieuze berichtgeving; Nepal Airlines - een Nepalese luchtvaartorganisatie, voorheen bekend als Royal Nepal Airlines; Republic of New Afrika - een zwart-nationalistische politieke beweging in de …

Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma.In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.Digestion is a form of catabolism that is often divided into two processes based on how food is broken …

RNAウイルスと宿主である人類とは共進化してきた。 ウイルスが生物のゲノムに内在化した痕跡である「ウイルス化石」としてはこれまでにレトロウイルスが知られる 。 生物はレトロウイルスの遺伝子をゲノムに組み込み、内在性レトロウイルス(Endogenous retrovirus, ERV) として遺伝し、ゲノムの ...

DNA. Secondary structure is the set of interactions between bases, i.e., which parts of strands are bound to each other. In DNA double helix, the two strands of DNA are held together by hydrogen bonds.The nucleotides on one strand base pairs with the nucleotide on the other strand. The secondary structure is responsible for the shape that the nucleic acid assumes.

Positive-strand RNA viruses (+ssRNA viruses) are a group of related viruses that have positive-sense, single-stranded genomes made of ribonucleic acid.The positive-sense genome can act as messenger RNA (mRNA) and can be directly translated into viral proteins by the host cell's ribosomes.Positive-strand RNA viruses encode an RNA-dependent RNA polymerase (RdRp) …

Nucleic acids are biopolymers, macromolecules, essential to all known forms of life. They are composed of nucleotides, which are the monomers made of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base.The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). If the sugar is ribose, the polymer is …

Messenger-RNA (in het Nederlands af en toe boodschapper-RNA genoemd), dat meestal afgekort wordt tot mRNA, speelt een centrale rol in het tot expressie brengen van genetische informatie.Messenger-RNA is een vorm van RNA die als 'boodschapper' (messenger) twee processen met elkaar verbindt: de transcriptie, waarbij een stuk DNA (een gen) overgeschreven …

Le séquençage de l'ARN (RNA-Seq, de l’anglais RNA sequencing), également appelé séquençage aléatoire du transcriptome entier (whole transcriptome shotgun sequencing en anglais) [1], est une technologie qui utilise le séquençage à haut débit (next-generation sequencing en anglais) pour identifier et quantifier l'ARN issu de la transcription du génome à un moment donné [2].
