	Roses for Rosalind
	This piece is an homage to Rosalind Franklin, the x-ray crystallographer who produced extraordinarily clear photos of crystalline DNA in 1952. The DNA structure which James Watson and Francis Crick proposed in the March 1953 journal Nature is largely based on Rosalind's experimental work. On this quilt, in addition to the images of Photo 51 (see below) in three different sizes, there are 2 depictions of the double helix, human chromosomes printed in the border, and DNA sequencing (of nucleotide sequences) from my husband's research.

	This is an image of Photo 51, Rosalind Franklin's x-ray crystallograph of DNA structure B. Apparently to those who know what they're doing, the helical structure is obvious in this photograph! This was published in the same issue of the journal Nature as the famous Watson and Crick article.	The layout of Roses for Rosalind comes from this stamp, "Geometric Design 1", used with permission from Rubber Tree Stamps.
