She is also certified in secondary special education, biology, and physics in Massachusetts. Cite this lesson In this lesson, we'll discuss the structure of the cell membrane and how this influences diffusion. Then, we'll give three examples of substances that can move by diffusion alone ...
Signaling molecules have multiple kinase and phosphatase regulators, and gene promoters can be simultaneously influenced by both positive and negative transcription factors. Ligands, of course, are themselves subject to myriad control systems.Jeffrey M. Perkel...
(Biology) A sequence of RNA produced by transcription. Manuscript A version of a book, article, or other work before being published or prepared for publication The author submitted the manuscript as a text file. Transcript Something which has been transcribed; a writing or composition consisting ...
(Biology) A sequence of RNA produced by transcription. Script A style of type that imitates handwriting. Transcript Something which has been transcribed; a writing or composition consisting of the same words as the original; a written copy. Script The matter set in this type. Transcript A copy...
the main component of the transcription unit, contains the actual exons and introns. Theterminator, a sequence of nucleotides at the end of the transcription unit, is transcribed along with the RNA coding region. The terminator serves as a speed bump of sorts; transcription stops only after this...
As a researcher who does synthetic developmental biology, I'd add another example of a predictive model that would be very useful: can we predict the developmental effects of a biological perturbation (such as expressing a protein in a certain cell type, mutating a transcription factor binding si...
thetranscription rates are presumed to be similar, at any given time, theconcentration of various crRNAs in the cell would be multiple times higher thanthat of the enzyme. It has been experimentally shown that with sufficientconcentration of a new crRNA molecule, it is able to displace the ...

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,...
