Phylogenetic utility of the mitochondrial cytochrome oxidase gene: molecular evolution of the Drosophila buzzatii species complex.

abstract：:We have investigated the evolvability of an insoluble random polypeptide, RP3-34, to a soluble form through iterative mutation and selection with the aid of the green fluorescent protein (GFP) folding reporter. To assess the solubility of the polypeptides in the selected clones of each generation, the polypeptide gene...
