replication- DNA is used as a template to make more DNA, resulting in 2 DNA molecules each with one old and one new strand. In transcription DNA is used as a template to make RNA (mRNA). In translation the sequence of mRNA is decoded into a protein...

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 (
which leads to a7-methylguanosine 5′ cap(Fig. 5.6). The 5′ cap has several functions including making mRNA distinguishable from other types of RNA molecules, regulation of nuclear export, prevention of degradation byexonucleases, promotion of translation and promotion of 5′ proximal intron exci...
In subject area:Biochemistry, Genetics and Molecular Biology Transcriptional regulation is the primary event in the process of DNA transcription into messenger RNA and the following translation into a protein. From:Advanced Drug Delivery Reviews,2001 ...
However, the overall level of poly(A)+ hamster mitochondrial RNA from these hybrids was significantly reduced compared with that from the hamster parent. The hybrid cells also lacked several poly(A)+ RNA species found in the hamster parent, but contained additional minor transcripts. The ...
transcription–translation coupling changes the gene expression level inE. coliRNAP transcription. We measured the mRNA expression level ofE. coliRNAP-driven strains using RT-PCR (Supplementary Fig.15). Indeed, LacZ mRNA with the RBS was expressed at a 36-fold higher level relative to LacZ ...
II. Translation itself is not saturated either, but may be downregulated as secretion efficiency drops. III. Two explanations for the previously reported drop in secretion efficiency for the recombinant protein with increasing expression level are possible: A. Protein degradation is an alternative fate...
Prokaryotes do not have membrane-enclosed nuclei. Therefore, the processes of transcription, translation, and mRNA degradation can all occur simultaneously. The intracellular level of a bacterial protein can quickly be amplified by multiple transcription and translation events occurring concurrently on the ...
