And by saying that the life comes from comets, you're just pushing the problem further away and further in time, but the question still remains. But it is true, that each comet/asteroid could have brought other compounds and when they mixed h...

What I did was to draw several lines each with marking the placeswhere the enzymes must cut and space in between X must be Xho obviously as it gives exactly one band of the same size so X + E gives |-------0,7----|-----------1,7----------| X + B gives |------2,3--------------------|---0,1--| B + E g...

Well, the standard way is to filter the water and keep the filter on some growth medium to see how many colonies will form. However, not every growth medium will suit every bacteria and some bacteria are unculturable in general. More precise way is to do 16S RNA sequencing, but I'm not sure if that ...

I've never heard about Mn in PCR (which doesn't mean it's not used) and to my knowledge they always provide magnesium, but there are proteins which work better with one or another (e.g. pyrophosphatase is specific for pyrophosphate with one metal while with the other it can cleave also other substra...
