Spider silk can conduct electricity. Some spiders use this material property of conductivity to capture prey. https://www.ncbi.nlm.nih.gov/pubmed/24323174 So I'm going on the assumption that both electrical lines spanning the web are bare and that they are live, i.e. carrying current. I will also assume that these lines are carrying the same current. With ...

I am not an expert on expression of genes from viral vectors, but as I requested the poster to clarify his question I feel an obligation to provide at least a partial answer. The first question to address is whether the mRNA for the protein of interest is expressed in the same way as normal cell proteins. In the case of the lentovirus vectors which are ...

There are various proteins sensitive to changes in electric field. More precisely, they are activated by changes in voltage (surrounding the protein), and immersed in water, as all cells are mainly composed of an aqueous solution. You are correct that most charges in the side chains of the proteins' amino acids are 'masked' by the dipole character of water ...

In addition to what is already said, I want to mention something more subtle. What other people have commented here is about an old 'dogma' due to Christian Anfinsen, which postulates that all that matters is the sequence of aminoacids + the microenvironment (pH, temperature, etc). However, I think you might be confounding two other layers of biochemical ...

As you mentioned water is a dielectric and because of that and the presence of ions in solution, electrostatic forces have a very short range inside a cell. If you apply a potential difference (voltage) in solution, you will generate a constant electric field between the two electrodes. Proteins will respond to this electric field by moving towards the ...
