【13】The first step of transcription is called pre-initiation. RNA polymerase andcofactors(general transcription factors) bind to DNA and unwind it, creating aninitiation bubble. 转录的第一步称为预启动。RNA 聚合酶和辅助因子(一般转录因...
生物信息的传递-Transcription——从DNA到RNA精选全文完整版
●基本概念●转录起始：RNA聚合酶、启动子●转录的基本过程●转录后加工●原核生物与真核生物mRNA的特征比较●RNA合成与DNA合成异同点 思考题？一、基本概念与基本特征 转录(transcription)：基因转录是在细胞核内进行的。它是指以DNA的一条链为模板，按照碱基互补配对原则，合成RNA的过程。转录 DNA RNA 参与转录的...
英文:Within the cell, mRNA is converted into proteins through the process of translation, which is fundamental to life activities. 英文同义表达: DNA Replication: DNA duplication Replication of DNA Transcription: RNA synthesis Transcription process Translation: Pro...
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...
Gene Expression I (Transcription and RNA Processing): How Is Information Transferred from DNA to RNA?As we have learned, genes are sections of DNA that contain information, information which is ultimately expressed through the processes of transcription and translation. Although genes are sections of...

RNA is present in lower and simple organisms, and DNA is in higher and complex organisms. Answer and Explanation: Transcription is associated with DNA to RNA. Transcription is the process of forming RNA from DNA with the help of the RNA polymerase enzyme. On the......
DNA Transcription to mRNA - DNA is a double-stranded structure found in eukaryotes (multi-cell organisms) whereas RNA (Ribonucleic acid) are single-stranded structure found in prokaryotes (single-cell organisms like bacteria). During transcription, the D
逆转录(reverse transcription)逆病毒(retrovirus)在宿主细胞中能以其RNA为模板合成DNA,称为逆转录以RNA为模板合成DNA的过程,与通
