Before DNA was definitively shown to be the genetic material in cells, scientists proved that

DNA carried and made copies of information.

Frederick Griffith used two strains of pneumonia in his experiments called

S-strain and R-strain (S-caused disease)

Which researcher(s) used radioactive markers to show DNA was the genetic material in cells?

Alfred Hershey and Martha Chase
