    What does HC3 mean in 'His HC3'?

    My lecturer said it means: "3rd residue, C-terminal to Helix 'H'" but that makes no sense. If it's the 3rd residue then it can't be on the C-terminal, because the C-terminal is at the end of a massively long sequence of residues. Visa versa if it's on the C-terminal then it can't be the 3rd...

    A Radioisotope-induced radioactivity in a protein molecule

    Dear Forum Members, I am a molecular biologist. One of my projects is focused on the identification of a protein that interacts with a known organic molecule. Namely, I try to chase a transmembrane protein that is known to transport one organic acid. If possible, I would like to get an idea on...

    Different lengths of genes expressed

    I was wondering whether it can ever happen that only a certain "length" of the same gene gets expressed in different species? Or perhaps even within the same species? (Without it being a random mutation) Basically, can a part of a gene be expressed, and still have some functionality in the...

    Protein melt temp/half life relation?

    Is anyone familiar with a way to determine the half-life of a protein from its melt temperature (Tm)? It seems like there ought to be some sort of correlation, be it theoretical or empirical.

    Medical Are there any other Macronutrients?

    I have a few questions on energy from foods. Do we have any other macronutrients that contribute energy to the body other than carbohydrates, proteins and fats in our body? What is the role of Hydrochloric acid (HCL) in our stomach? Is the HCL involved in all three above macronutrient digestion?

    Gene and its protein term?

    Hello again! Is there a common word/term for a gene and the protein that it codes for? I know there is signal transduction, but that would be for a whole set of genes and proteins doing a stream of functions. But would there be a name for the specific gene/protein "bundle"?

    Other Statistical Physics and Biology

    I'm undergrad physics student and I have read some statistical physics like equilibrium statistical physics, Langevin model and Fokker-Planck equation. I have developed interest in application of statistical physics in biology like protein folding. So what are the other research topics that lie...

    Proteins that duplicate the DNA in interphase

    For some reason, I can't seem to be able to find this answer easily on the internet. Or it is there and I somehow I can't see the wood for the trees. I know that in transcription (when DNA is read for protein production), "RNA polymerase" is the protein that creates the mRNA by creating the new...

    Genes coding for cells?

    My understanding is that genes code for proteins that then do a certain function. Apart from mitosis in an organism, I heard that cells (in forms of stem cells) are also produced and released into the body. I guess these would be all the floating around the body cells? Or the nerve cells that...

    What happens to a protein built from mutated RNA?

    I was wondering if anyone knew what happens to a protein that gets wrongly assembled due to a mutated RNA? Does it just do a slightly different or very destructive action in the organism, or does the organism catch it and kick it out? Also an extra side question: Speaking of mutations of RNA...

    Genes and protein they code size relation?

    If the gene is smaller, is the protein that it codes for smaller too? Vice versa?

    Methods of Regulating Proteins

    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...

    Biophoton Emission Outside Visible Range

    There are a lot of florescent proteins in the visible range, but why haven't we fount any above or below that range? I think a protein that emits radio waves could be very helpful both biologically and scientifically. Are we not looking for such proteins, or do they not exist?
