Physical Mapping 



Chromosome-19 contig map 

 as of October 1989. Of the 



2200 cosmids processed for 

 fingerprint analysis, over 900 

 of thiem are in contigs with an 

 average contig length of about 

 3 cosmids. Selected cosmid 

 contigs are shown in this figure 

 with their map location as 

 determined by fluorescence in 

 situ hybridization. Each cosmid 

 is designated by its clone 

 number; bold numbers repre- 

 sent the "minimal" covering 

 set for that contig. Contigs 

 associated with known genes 

 are in ovals, and the gene 

 designation is indicated above 

 each oval. The graph at the 

 bottom of the figure shows the 

 rate of contig formation.
