Individual chromosomes provide the skeletal framework on which genomic data is organized.
As the physical map and an ordered assemblage of molecular clones for chromosome 16 nears completion, we have embarked on the construction of an 'expressed sequence map' of the chromosome. To this end we have chosen the strategy of exon amplification to identify expressed sequences on chromosome 16. Our strategy employs 96-well plate pools of DNA from the flow sorted and arrayed chromosome 16 cosmid library as the substrate for exon trapping. At present we have generated 1800 exon clones from 75 of the 150 plates in the chromosome 16 library. These sequences are being mapped to specific locations on chromosome 16 using a panel of somatic cell hybrids and molecular clones.
