Other Cetus scientists who were regarded as "top-notch experimentalists", including Randall Saiki, Henry Erlich, and Norman Arnheim, were placed on parallel PCR projects to work on determining if PCR could amplify a specific human gene (betaglobin) from genomic DNA. Saiki generated the needed data and Erlich authored the first paper to include utilization of the technique, while Mullis was still working on the paper that would describe PCR itself. Mullis' 1985 paper with Saiki and Erlich, "Enzymatic Amplification of β-globin Genomic Sequences and Restriction Site Analysis for Diagnosis of Sickle Cell Anemia" — the polymerase chain reaction invention (PCR) — was honored by a Citation for Chemical Breakthrough Award from the Division of History of Chemistry of the American Chemical Society in 2017.
