Re: Purpose of a primase/polymerase localized to the cytosol?

... be a long surviving vestigial remnant of bacterial ancestry. It might be helping maintain proper levels of environmentally uptaken DNA e.g. via transformation, for successful establishment (integration into genome and maintaining enough copy number) & functioning of the uptaken DNA in those ...

How does DNA cladistics work???

... cladistics (i.e., based on morphological data). So, for example, a sequence of a given gene is obtained for different species and the number of transformation in the sequence required for every possible phylogenetic tree is calculated. The phylogenetic tree that requires the lowest number of ...
