Academic career

As Pardue later described the process, her search for a faculty position in the early 1970s coincided with broad interest in United States academic institutions in hiring women, and she was surprised to be heavily recruited. After initially being rejected by MIT, she was subsequently offered an associate professor position there and accepted it in part because other offers were for more junior

performs much the same function. Her work is believed to be evolutionarily related to telomerase-generated telomeres, which highlights the theory that parasitic transposable elements could have possibly evolved from mechanisms in the cell that exist to maintain chromosomal health. Pardue's 1969 publication entitled ''Molecular hybridization of radioactive DNA to the DNA of cytological preparations,'' focused on the radioactive DNA localization in the nuclei of ovarian cells in ''Xenopus''. Through her work, she was able to conclude that the localization of binding in the oocytes of ''Xenopus'' is specific. Pardue also found that hybridization reactions with radioactive DNA were able to discriminate between different types of DNA.
