    Rationale of gene location on chromosome

    What I meant is that if a particular gene has to be expressed for certain essential functions of the organism, it is of little consequence whether it is located on chromosome A or chromosome B. Ultimately, all the housekeeper genes are not located only on a few particular chromosomes, they are...

    Rationale of gene location on chromosome

    Though it may not have significant implications on the function of the gene, its location on a particular chromosome and absence on an other is certainly interesting as it may offer clues as to how the human genome was shaped during evolution...(DNA assimilation and so forth.) and it certainly...

    How did eukaryotic cells evolve?

    Hi! I came across the concept of endosymbiosis being the way by which eukaryotic cells evolved and that all cell organelles are remnants of prokaryotic cells that lost their ability to survive independently. Is this just speculation or is there a solid scientific basis to this claim? Can anybody...

    How do opsin proteins control the spectral sensitivity of 11-cis-retinal?

    There are supposed to be different pigments with different photo sensitivities present in each of the different types of cones present in the retina. Assuming that there are three types of cones each sensitive to one type of primary colour, that would give us three pigments- chlorolabe(green)...

    Myocytes and neurones, initiating activity.

    Perhaps the first AP is generated from sensations carried to the brain via the thalamus and reticular formation. Since the thalamus is usually the one maintaining the basal electrical rhythm, I suppose it was the one that initiates it when the CNS first starts functioning. The neuron may have an...

    Regulating Blood Flow: The Role of Precapillary Sphincters

    That's my opinion as well.. capillaries, so far as we know, do not exhibit any from of constriction or dilatation. Its the precapillary sphincters containing smooth muscle in their walls that constrict and hence regulate the flow of fluid through them.
