During transcription, the DNA is converted into RNA inside the nucleus of a cell. Once converted the messenger RNA (mRNA) comes out of the nucleus and the translation process starts in the cytoplasm of the cell to produce protein.If the DNA is considered the genetic code, it has to be ...
Transcription is the flow of genetic information from DNA to RNA. It is A process of synthesizing RNA catalyzed by RNA polymerase with A,U,C and G ribonucleotides as raw materials using A certain chain of double stranded DNA (template chain...
Transcription, the synthesis of RNA from DNA. Genetic information flows from DNA into protein, the substance that gives an organism its form. This flow of information occurs through the sequential processes of transcription (DNA to RNA) and translation (
以DNA为模板,在RNA聚合酶作用下合成RNA的过程 promoter启动子(promoter): 与基因转录启动有关的特定保守序列;启动子本身不被转录 transcription factor反式作用因子 又称调节蛋白(DNA结合蛋白DBP,或转录因子TF) 基本转录因子:是RNA聚合酶结合启动子所必需的一组蛋白因子,决定三种RNA(mRNA、tRNA及rRNA)转录的类别。 特...
1、转录 (transcription) 从DNA到RNA,Chapter 3,OUTLINE,3.1 转录过程的概述 3.2 转录机器的主要成分:RNA聚合酶和转录复合物 3.3 原核生物基因的转录 3.4 真核生物基因的转录,基因表达,基因表达包括:转录和翻译 转录:拷贝出一条与DNA序列完全相同的RNA单链的过程,由RNA聚合酶催化,通过互补碱基配对来合成RNA。 翻...
1、 Transcription The synthesis of RNA molecules using DNA strands as the templates so that the genetic information can be transferred from DNA to RNA.TranscriptionBoth processes use DNA as the template.Phosphodiester bonds are formed in both cases. Both synthesis directions are from 5 to 3. ...
