During transcription, when does RNA polymerase lave the DNA molecule? a. When it reaches the terminator. b. When it reaches the promotor. c. When it reaches the stop codon. d. When it reaches the start codon. e. When it sep...
A UAS was identified upstream from the translational start codon of the rocDEF operon, which is similar to the rocABC operon23. The sox locus in Bt also has three promoters (Fig. S3), two of them are regulated by the Sigma54 factor. The soxB and soxC genes have conserved −12/...
26 A RA-response element located at position −1375 relative to NIS start codon mediates the activation of NIS expression by tRA in human follicular thyroid carcinoma cells.27 NIS regulation by retinoids in breast cancer cells is effected through a downstream intronic enhancer, which binds RARα...
The stop codon within exon 9 is also indicated (TGA, red arrow). (b) Three mRNA variants are generated. ATG1 forms OCLN variants 1 and 2, each of these two variants has a different transcriptional start site. ATG2 generates OCLN variant 3. (c) OCLN variant 1 and 2 translate into ...
crescentus response to chromium and cadmium stresses, we monitored expression of CC3255, previously identified as a σF-dependent gene, as well as CC3252, which is co-transcribed with sigF (CC3253), by quantitative RT-PCR. This analysis showed that CC3255 is significantly induced in parental ...
Consequently, MalR plays a crucial role in both substrate induction and glucose repression of maltose utilization. malR is expressed from a single promoter with transcription initiating at the first G of the predicted GTG translation start codon. 展开 ...
falciparum genome are located within 500 bp of the translation start site, we used the 500 base pair region directly upstream of the translation start codon to compute nucleosome characteristics of promoter regions. To avoid overlap of these promoter regions with gene regions, only genes that are ...
The base is cytosine. It is found in both DNA and RNA. The given base is a pyrimidine as it contains only one ring. Based on the types of atoms... Learn more about this topic: Nucleic Acid | Function, Structure & Importance
This led to the identification of at least five new transcriptional start sites located upstream of the EσE-transcribed promoter. The presence of multiple authentic promoters was confirmed by in vitro run-off assays and the construction of the single-copy promoter fusion to individual promoters. ...
Two mRNAs differing in size (2.4 and 2.7 kb) are transcribed from the murine Bf gene as a result of alternative transcriptional initiation at two sites separated by 302 bp (18). The downstream transcriptional initiation site (DIS) is located 105 bp 5′ to the Bf open reading frame at a ...
