Abstract
We describe an approach to detect the frequency of interaction between any two genomic loci. Generation of a matrix of interaction frequencies between sites on the same or different chromosomes reveals their relative spatial disposition and provides information about the physical properties of the chromatin fiber. This methodology can be applied to the spatial organization of entire genomes in organisms from bacteria to human. Using the yeast Saccharomyces cerevisiae , we could confirm known qualitative features of chromosome organization within the nucleus and dynamic changes in that organization during meiosis. We also analyzed yeast chromosome III at the G 1 stage of the cell cycle. We found that chromatin is highly flexible throughout. Furthermore, functionally distinct AT- and GC-rich domains were found to exhibit different conformations, and a population-average 3D model of chromosome III could be determined. Chromosome III emerges as a contorted ring.

- The cross-linking is mediated by DNA bound proteins and thus the local protein density will affect the cross-linking efficiency. As is clear from Fig. 3 the parameter k (in Eq. 1) which reflects this efficiency appears to vary slightly along the length of chromosome III. In addition a high local digestion efficiency or a favorable geometry of the cross-linked intermediate will also influence the amount of ligation product formation and thereby the apparent cross-linking frequency. However as is apparent in Figs. 2 and 3 these effects are minor.

) - The flexibility of chromatin in higher eukaryotes is not firmly established. FISH analysis of mammalian chromosomes yielded values of l [ l = 137 to 440 nm (27) and l = 196 to 272 nm (42)] whereas detailed in vitro experiments with single chromatin fibers from chicken erythrocytes yielded lower values of l [ l = 60 nm (43)].
- The local concentration is maximal for sites separated by ∼1.7 times the statistical segment length l. We estimate that the contour length of the yeast chromatin fiber is 11.1 nm/kb. A segment length of 56 to 69 nm (as determined in Fig. 3 A and B) will then correspond to 5.0 to 6.2 kb. The local concentration is therefore maximal for sites separated by 8.5 to 10.5 kb.

- Given a table of all distances between n + 1 points one can find a constellation of n + 1 points in three dimensions satisfying this distance table with the use of the following algorithm which is based on Cholesky decomposition of symmetric matrices. The distance table can be converted to a symmetric n × n matrix M that contains all the inner products of the n + 1 points in n -space. If the distance table describes a 3D structure M should have rank 3. In general however M does not have rank 3 because of noise in the data. By slightly moving M in n 2 -space we obtain a matrix M′ close to M which does have rank 3. This is done by setting all but the three largest eigenvalues to zero. Indeed three eigenvalues we determined were considerably larger than zero and the other had very low values which indicates that the M is very close to a matrix with rank 3. This is strong support for the accuracy of the distance calculation. Cholesky decomposition of M′ will yield the positions of the n + 1 points in three dimensions and the distances between those points will nearly satisfy the experimental distance table. By using M′ instead of M we introduce an error which is related to the error in the data of the experimental distance table. The distance between M and M′ is a measure for this error and was found to be only about 6%.
- The FJC model will give a reasonable approximation of j M for values of s larger than 3 to 4 times the statistical segment length which for a value of l = 56 to 69 nm and a contour length of 11.1 nm/kb corresponds to 15 to 20 kb. For sites separated by less than 3 but more than 1.7 statistical segments (corresponding to site separation distances of 8.5 to 15 kb) Eq. 3 will yield a value of r that is slightly too high but the highest deviation is about 20% (9). Because only 2 of the 78 site separations were smaller than 15 kb (12 and 13 kb) the set of 78 cross-linking frequencies presented in Fig. 3A could be used to estimate the average spatial distances between the respective sites according to Eqs. 1 and 3 with good accuracy. For k the chromosome-wide average value of 4.0 × 10 6 M −1 was used which was determined by fitting the chromosome-wide data set to Eq. 2. Because the analysis of AT- and GC-rich domains (Fig. 3B) revealed small local variations in the value of k this might introduce small errors (at most 10%) in certain regions of the chromosome.

- In some cases a very small amount of ligation product was detected in the absence of cross-linking but this was always 5% or less than the amount detected after cross-linking with 1% formaldehyde.
