Paradigm shifts. Part II. Reverse Transcriptase. Analysis of reference   stability and word frequencies
  The reverse transcription paradigm shift in RNA tumor virus research marked by the discovery of the reverse transcriptase in 1970 was traced using co-citation and title word frequency analysis. It is shown that this event is associated with a break in citation patterns and the occurrence of previously unknown technical terms.
