Phylogenetic relationships and altered genome structures among Tetrahymena mitochondrial DNAs.

abstract：:RNA:5-methylcytosine (m5C) methyltransferases are currently the focus of intense research following a series of high-profile reports documenting their physiological links to several diseases. However, no methods exist which permit the specific analysis of RNA:m5C methyltransferases in cells. Herein, we described how a...
