Method "For definition of gene structure, [researchers] relied on the use of different gene-finding approaches: the gene-finding programs Genscan (17) and a version of Genie that uses expressed sequence tag (EST) data (18), plus the results of complementary DNA (cDNA) and protein database searches, followed by review by human annotators (19)."
Comments "[Researchers'] annotation of the Drosophila genome predicts 13,601 genes, encoding 14,113 transcripts through alternative splicing in some genes." "The total number of protein-coding genes, 13,601, is less than that predicted for the worm C. elegans (27) (18,425. WormPep 18, 11 October 1999) and far less than the ~27,000 estimated for the plant Arabidopsis thaliana (28)." See BNID 104993. For value of 14,332 proteins see BNID 105464 Table - link
