Why similar features are preserved in a gigantic population?

... East Asians, Chinese, Koreans, Mongolians and Japanese (except the native Ainu) resemble each other. All have common characteristics as epicanthic fold, oblique eyes, slightly marked brow ridges, flat face, high orbits, etc. .. The teeth are Characterized by sinodonty.

Graphs depicting qPCR fold change

I am interested in hearing people opinions about what is the best/accepted way to display the fold change values in a graph, specifically the fold change axis scale? I have seen it presented in one of 2 ways 99% of the time, but neither of these are ideal as far as I can ...

Just a short question. I always thought "the mutational rate of mtDNA is ten fold higher than that of nuclear DNA" and now I read "Although much more slowly, mitochondrial DNA does mutate". Which one is true then? Maybe some references from an ...

protein fractionation

... just have to try different approaches and detect both your protein (enzymatic activity?, blotting...) and total protein and determine purification fold. Great for you would be the first chapters from methods in Enzymology 463 http://www.sciencedirect.com/science/bookseries/00766879/463

Re: How did endosymbionts coordinate replication?

... it as an organelle. So, I suppose, in any eukaryotic cell the mtDNA should be relatively conserved. However, the mutational rate of mtDNA is ten fold higher than that of nuclear DNA. So is the mtDNA sequence conserved among e.g. various mammalian species or the opposite?
