Where in the cell does transcription take place? Which region of transcription has premotor? What is accomplished in the process of transcription? What is being copied, and what form does the copy take? What doe
Circulating inflammatory mediators can signal neurons through a pathway in which cytokine activation of the cells of the blood-brain barrier causes the induction of the nuclear factor kappa B (NF-B), leading to the transcription of target genes, such as the one encoding cyclooxygenase 2 (COX-2...
occasionally arises a left-handed form of DNA that scientists have called “Z-DNA”. (Fortunately, Z does not mean zombie, however it is only a matter of time until a comic book writer uses it that way.) It seems to occur briefly during biological activities such as DNA transcription. ...
In the presence of a DSB induced by Cas9, cells can also repair themselves via HDR, and this pathway offers an opportunity for researchers to insert a new piece of DNA or an entire gene. This method is known as a gene knock-in. ...
Molecules associated with regulatory T cells The immunosuppressive function of Tregs depends on continuous expression of the transcription factor Foxp3, which is also a hallmark of the completion of Tregs differentiation [25]. Foxp3 controls the proliferation, inhibitory function and homeostasis of Treg...
Reverse Transcription Quantitative PCR (RT-qPCR) Two methods are available for quantification of gene expression by RT-qPCR: two-step RT-qPCR and one-step RT-qPCR. In both cases, RNA is reverse transcribed into cDNA, and the cDNA is then used as the template for qPCR amplification. One-ste...

is a transcription/translation feedback loop that anticipates day/night cycles to optimize organismal physiology. We now know that circadian disruption is widespread and increases the risk of cardiometabolic disease. Circadian rhythms ...
What is involved with the initiation of transcription? How do transcription enzymes know the sequence of DNA that is to be translated into a required protein? Name the three enzymes involved in DNA replication and their function. Name the two enzymes involved in a replication of DNA. ...
includingimage recognition, predictive modeling, decision-making and natural language processing (NLP). Examples of significant commercial applications over the past 25 years include handwriting recognition for check processing, speech-to-text transcription, oil exploration data analysis, weather prediction and...
