By January 1953, Franklin had reconciled her conflicting data, concluding that both DNA forms had two helices, and had started to write a series of three draft manuscripts, two of which included a double helical DNA backbone (see below). Her two A-DNA manuscripts reached "Acta Crystallographica" in Copenhagen on 6 March 1953, one day before Crick and Watson had completed their model on B-DNA. She must have mailed them while the Cambridge team was building their model, and certainly had written them before she knew of their work. On 8 July 1953 she modified one of these "in proof" "Acta" articles, "in light of recent work" by the King's and Cambridge research teams.
