1. 转录(Transcription):转录是指DNA序列被RNA聚合酶(RNA polymerase)复制成RNA分子的过程。在细菌中,RNA聚合酶结合到DNA的启动子区域,并沿着DNA链合成相应的mRNA分子。转录过程包括启动、延伸和终止阶段。 2. 剪接(Splicing):在某些细菌中,mRNA可能还需要经过剪接过程。剪接是指将mRNA中的内含子(intron)区域切除,保...
I have obtained evidence that early vaccinia mRNA is made by monocistronic transcription in vitro , by comparing the relative sensitivity of the synthesis of individual messages to ultraviolet irradiation. Production of mRNA was assayed indirectly using a coupled cell-free transcription–translation ...
True or False: In bacteria, transcription of a mRNA molecule and its translation can happen simultaneously. Explain. RNA processing enzymes are directly recruited to the growing mRNA strand via the 5' cap during eukaryotic transcription. a) True b...

For mRNAs produced by in vitro transcription (IVT), two major methods are used for capping the molecules. First, a cap analog called ARCA (anti-reverse cap analog) may be added by replacing the 3’ hydroxyl group of m7G with a methoxy group. ARCA-capped mRNAs generally have relatively high...
poly(A) tail对维持mRNA的稳定性起着重要作用,体外合成mRNA常用的加尾方式有两种:(1)在IVT(in vitro transcription)后利用poly (A) polymerase进行加尾;(2)质粒模板上设计poly (A)序列,在IVT时被转录出来从而带上poly (A)尾,由于成本低,工艺简便,这...

Transcription of genome-encoded information into mRNA and translation of mRNA into a functional protein are the main layers of gene expression. Due to the existential need to adjust gene expression to both intracellular requirements and extracellular stimuli, both processes are subject to regulation at...
PROBLEM TO BE SOLVED: To provide a translation promoter capable of shortening 5'UTR. A translation promoter used in a cell-free protein synthesis system, the translation promoter is a 5'non-translation region linked adjacent to the 5'end of a coding region encoding the amino acid sequence of...
