Refer to the paragraph on the Venter et al. paper and the table above. Because DNAs for sequencing were chosen at random with no way of knowing which organism they came from, how could genes be identified?

A) by searching for open reading frames (ORFs), especially those with translation start and stop sites
B) by searching for similarity between predicted ORFs and those in existing databases
C) by searching for exons bounded by consensus donor and acceptor splice sites (those that mark exon/intron boundaries)
D) by searching for ORFs, particularly those with translation start and stop sites, as well as for similarity between predicted ORFs and those in existing databases
