Collaboration and Competition-, Rosalind Franklin's Story

If one were onlv to encounter Janles Watson's depicrion of Rosalind Franklin in ThcDouble Helix, the,v rvould bc left rvith an inaccurate portrait of a difficult and con-lrontational scientist. ivho lacked the intellect to understand her own data.Fortunatel,v, Anne Sayre in Rosalind and DNA, and later, Brenda lv'laddox in RosalindFranhlin: TIte Dcrrh Lady of DNA, provide insights into Franklin's character and helpil luminate her irnporternt contribution to the understanding of double-helical DNA.

InJanr.rar,v 1951. after spending four years working in a French nzrtional chemistrylaboratory Franklin.;oined J T. Randells biophysics research group at King's Collegein London. It is rvell knorvn that Franklin did not get along lvith Maurice Wilkins,assistant director of the biophysics r"rnit, although he s'as a natural candidate for col-laboration given that he. l ike Frirnklin, rvas assigned the task of using x-ray crystal-lography to obtain diffraction photographs of DNA fibers.

Despite the challenges she iaced at King's College, Franklin produced superb x-rar'photographs of DNA.

data anti "evcr\.thing in her education and b:rcliground had tau.ght her to be absolutel,v snre o[ her f:rcts before she prcsentedtheur to tht- u.orld" (Nieddox. 178).

Frirnklins crit ical mist:rke u.as a faih.rre to recognize tlre significance of the uronoclinic C2 s,vlnmetry in the diffractron pat-terns of her "8" DNA. When Crick discovered this in the ivlRC report, he realized that this connoted anti-parallel strands.Combined \\'ith \\;atson's revelations about horv thc bases paircd, the trvo men were able to nrake the intuitit'e le,rp and comeup rvith the idea that anti-parallel strands could serve as templates for eirch other in a reprlication scenario. It is questionable,even if she hird fully understood her data, u'hether Franklin rvould have ever made this connection. She "had been trained, asa child, as a Par.rl ina, as an undergraduate, as x scie ntisL, nevL'r to overstate the case, nel'er to go bevond hard evidence. Anou{-rageous leap of the iniagination r.r'ould have been as out o{'character as running up an overdraft or lvearing a red straplessdress" (Maddox, 202).

In the end, are we to believe that Franklin \ /as a victim o[ her education and training, never encouraged to rake daringchances? While this is a possibilit)', g'hat we krlovg for sure is that she "provided all of the essential data for those who tookthe two bril l iant leaps o[intuit ion-to anti-parallel chains and base pairs-that cracked the problem" (Maddox,202).Franklin rvas an excelient experimentalist and h.er data rvere "[undamental to the discovery".(Madclox, 210). Was she passedover for the Nobel prizel Perhaps. Hou'ever, it w-as "arvarded to \A/atson, Crick, and Wilkins four years after her death, and theprizes are never arvarded posthumously" (Creager, 66). Regardless, we can be certain that Rosalind Franklin is among a distin-gr-rished ferv rvho contributed to our basic knowledge about the double helix.
