What role do promoters play in transcription? Explain in detail. Describe transcription in your own words clearly but concisely enough that someone could visualize what is happening. Explain about the different steps involved in gene transcription process. ...
What role do activators, transcription factors, and the mediator play in transcription? What is the structure of the most common transcription terminator signal in E. coli, and what are 2 conserved features of the RNA sequence of this structure?
Transcription is the process of synthesizing RNA which is controlled through interactions of promoters and enhancers. During this process multiple types of RNA are produced, such as mRNA, tRNA, and rRNA. Answer and Explanation: Transcription is completed in four steps: ...
The study of IE (immediate-early) gene activation mechanisms has provided numerous paradigms for how transcription is controlled in response to extracellular signalling. Many of the findings have been derived from investigating one of the IE genes, FOS, and the models extrapolated to regulatory mechan...
What mechanistic role do adult-born DGCs play in behavioral pattern separation? Although the gross anatomical connectivity of the DG suggests a role in pattern separation, the DG’s ability to perform this function appears to be further enhanced via its ability to incorporate new neurons. Adult-...
Despite recent major advances in developing effective vaccines against toxoplasmosis, finding new protective vaccination strategies remains a challenging and elusive goal as it is critical to prevent the disease. Over the past few years, various experimental approaches have shown that developing an effectiv...
Barbara McClintock in the early 1980s proposed that TEs could be activated by a genomic shock, and this might have an adaptive value on the host genome. For a long time, they were considered as enigmatic sequences with an uncertain role in the genome. However, our comprehension of the ...
MMP promoters.The Activator Protein-1 (AP-1) site at approximately −70 bp upstream of the transcriptional start site has long been thought to play a dominant role in the transcriptional activation of the MMP promoters, particularly in response to stimulation with phorbol myristate acetate(PMA)....
What is transcription? Describe the process of transcription. Where does it occur? What enzyme(s) are involved? What is the product(s)? What effect do transcription factors have on a cell's proteome? What role do activators, transcription factors, and the mediator play in transcription?
The prokaryotic DNA polymerases have multiple enzymatic activities. What are these activities, and what role do they play in DNA replication? Which of the following is found in eukaryotic genes but not prokaryotic genes? a) introns b) repressors c) operons ...
