Gene expression Definition and 19 Threads

Hello everyone, I am interested in researching the underlying physics of gene expression. I'm a junior in a math/physics double bachelors program.

I've been struggling, no matter what I try to do I can't come up with a solution. The answer is in situ, but in my mind it would work perfectly fine. The only thing we would do is just use an RNA probe complementary to the gene we are trying to detect and it should light up the moment the gene...

Homework Statement A bacteria that normally divides every 20 minutes express gene X. The production rate of protein X is 5nM/min. The protein is stable and does not degrade. What is the concentration of X in the steady state?The same bacteria enter into a stress state at t=0 for 3 hours...

I've read in a few places that acetylation of histones creates transcription activation rather than repression (the common example being: H3K9). What I am curious, with the absence of this acetylation (I'm guessing this would the process de-acetylation), do the genes that were previously...

Today (AUG 1) is RNA Day, an international celebration of one of the most versatile biomolecules in existence. What are some areas of RNA research that excite you most? Some of the most intriguing areas of current research to me (with example links for further reading): The role of RNAs in...

There have been occasionally questions/comments about gene control. This should feed the hunger for knowledge. Here is an open access review article: Three-Dimensional Genome Organization and Function in Drosophila. It discusses some not widely known aspects of control of gene expression in...

How does the Gall Wasp get an Oak tree to make these? http://ento.psu.edu/extension/factsheets/galls-oak https://en.wikipedia.org/wiki/Gall_wasp I am not able to find anything other than "induced by chemicals secreted by the wasp" more or less. I have been looking at these over the last six...

I have been looking into different methods of regulating protein activity for a project. I think it is pretty interesting and I want to learn more about this. I want to learn about the different methods out there, if you know of any cool or helpful regulation techniques I would certainly...

Introducing myself. - After many years in various technical fields, I moved into the people-helping world with teaching and psychotherapy. Physics and medicine, of course, have always played important parts in my world. I would say, though, that mental processes including gene expression...

Take for example a fetus of 2 weeks old and a baby of 2 years old. The fetus doesn't show any limbs, skull. How do I know that is a human fetus ? :nb)

Mind-controlled transgene expression by a wireless-powered optogenetic designer cell implant. Kind of a sensationalized title, since it's really just interpreting brain waves through a BCI, but neat anyway. http://www.nature.com/ncomms/2014/141111/ncomms6392/full/ncomms6392.html

We have been doing research on the differential expression of one gene between two cell lines (A and B cell lines), with high expression in A cell line and no expression in B cell line. We found that ~250 bp in the promoter of the gene has its activity in A cell line, but no activity in B cell...

What makes us able to change the expression of some genes and unable to change the expression of other genes?

Hey guys, I've got a developmental question for yall. How would you experimentally compare gene expression during gastrulation in birds with that in frogs? I've been racking my brain trying to think of this, and the only way I can think of is to use a microarray, since it allows you to look at...

Question on Gene expression!? Explain how selective gene expression yields a variety of cell types in multicellular eukaryotes. Explain how eukaryotic gene expression is controlled, and compare it to gene control in prokaryotes. can anibody tell me the answers??! thanks :shy:

In a male, gender gene is expressed as XY, so people know how a male to be male by its Y, but in a female, the gene is XX, and I am wondering which one of XX is characterized for female... If the left one is, then what is the functionality of the right one ?

Can you tell me what exactly is gene expression ? I think it is the expression of a gene, correct ? By the way, I see my teacher usually sits in front of his computer, with a long page full of amino acids, I guess he might take it from somewhere's database, but do you know why people usually...

I was trying to find something about regulation mechanisms for expression of HSP genes, but no luck. Thing is I was thing about, maybe, possibility of thermo unstable repressor mechanism, but I don’t know how much that is possible. Any comments or information would be great.
