Expression and physical properties of screened genes are mostly representative of the whole transcriptome. Previously published datasets (Flymine) were used to determine if the collection of screened genes show any biases relative to the rest of the genome. (A) Distribution of expression levels in the screened genes are similar to the rest of the transcriptome in both the brain, and in the embryo. (B) While the length of 3′UTR extension in the screened genes is similar to the rest of the transcriptome, the screened genes on average have a longer total length and longer introns.
