5' Cap保护mRNA不被外切酶降解，与3'端的poly A尾、poly A结合蛋白（PAPB）和翻译起始因子蛋白协同作用，起始蛋白质的翻译。体外转录（In Vitro Transcription，IVT）的加帽是常用的加帽方式，可以在IVT时加帽（即共转录加帽），也可以在IVT结束后加帽（即酶法加帽）【详见mRNA体外制备之酶法加帽和共转录加帽...
Non-coding mRNA structures that sense the environmental status of a cell by directly binding to small molecule ligands, such as a metabolite or an ion. This interaction changes the RNA conformation and controls gene expression through alternative splicing, transcription or translation. Peptidyl transfera...

对于体外转录(In Vitro Transcription,IVT)合成的mRNA,常见的有两种加帽方法(图2):共转录加帽和酶法加帽,具体的加帽原理与步骤【详见mRNA体外制备之酶法加帽和共转录加帽】。但是应当注意共转录加帽会出现反向加帽的结果,从而导致快速的降解和较低的翻译效率。为了避免反向加帽,抗反向帽子结构类似物(anti-reverse...
Transcription rates impacts translation, Related to Figures 3 and 4 (A) Segregation of the induced versus non-induced Rluc mRNAs on sucrose gradients. Cells expressing barcoded Rluc gene were treated for 21 hr to induce the expression of Rluc or left untreated, and subjected to BPP procedure. ...
A. Transcription produces an mRNA molecule in the nucleus. The mRNA moves to the cytoplasm where translation occurs. B. DNA makes a copy of itself which is transportedProteins are made based on information stored in genes through the process of ......
This process is triggered by specific intracellular or extracellular signals leading to transcription of a single gene or a cohort of physiologically related genes in response to functional needs. Messenger RNA synthesis in bacteria is directly linked to the translation process since DNA, transcription ...
