Who isolated phosphate-rich chemicals/"nana" and called it nuclein or nucleic acids?

What experiment was widely accepted as a demonstration of bacterial transformation, whereby a bacterium distinctly changes its form and function? Streptococcus pneumoniae could transform from one strain into a different strain which he used 2 strands of this in his experiment
