What are the main differences between translation and transcription? What are transcription factors and why are they important? What is the process that turns on the transcription of a gene or genes? (a) What is the purpose of supercoiling? (b) How it is done in replication and transcription...
Transcription mechanismsAlthough we have made significant progress, we still possess a limited understanding of how genomic and epigenomic information directs gene expression programs through sequence-specific transcription factors (TFs). Extensive research has settled on three general classes of TF targets ...
Transcription factors are known to play a key role in regulating flux through pathways of secondary metabolism, by controlling the levels of pathway gene e... P Broun,Y Liu,E Queen,... - 《Phytochemistry Reviews》 被引量: 53发表: 2006年 Haematopoietic Stem Cells: What Regulates the Regulator...
These states are initiated by transcription factors that act at enhancers and are maintained by PcG and TrxG proteins at the PRE. Epigenetic memory is defined as the maintenance of gene expression states through cell generations in the absence of the initiating signals. PREs were first discovered ...
Such positive results are essential for the establishment of pluripotency induction through the incorporation of known transcription factors into the genome of somatic cells. 展开 关键词: Autoantibody Endometriosis Single nucleotide polymorphism Smoking Survivin DOI: 10.1111/rda.12002 被引量: 6 ...
Is there a role for trihelix transcription factors in embryo maturation? The development of the angiosperm seed includes the accumulation of storage products, the loss of most of its water and the establishment of dormancy. Whil... MS Barr,MR Willmann,PD Jenik - 《Plant Signaling & Behavior》...
Transcription initiation is a major regulatory step in eukaryotic gene expression. It involves the assembly of general transcription factors and RNA polymerase II into a functional pre-initiation complex at core promoters. The degree of chromatin compaction controls the accessibility of the transcription ...
Describe some of the general ways in which (specific) transcription factors are regulated and how they, in turn, can regulate gene expression What is meant by transcriptional gene regulation? What is the relationship between coding regions, promoters, regulatory genes/regulatory proteins /tra...
Although each one of your 37.2 trillion cells carries a copy of your DNA, not all cells build the same proteins. One reason for this is that molecules called "transcription factors" latch onto DNA to control which genes get switched on and off, and therefore, which proteins get made when,...
Domain-general mechanisms are evolutionarily ancient, resulting from the evolution of affective cues signaling the attainment of evolutionary goals. Explicit processing is a particularly important set of domain-general mechanisms for constructing human groupsenabling ideologies specifying future goal states and...
