Fluorescent In Situ Hybridization (FISH) Images of Annotated and Un‐annotated Gene mRNAs. One annotated gene and one un‐annotated gene from each of the two GO‐BP categories shown in Tables 2 and 3 were chosen and FISH images for those genes was retrieved from the FlyFISH database. Four different stage categories of early embryogenesis are shown. Green fluorescence represents the mRNA localization pattern for that transcript/gene and red fluorescence is showing the position of nuclei within the organism at that stage. CG1584 = Orc6, Origin recognition complex subunit 6. Its molecular function is described as DNA binding and it is involved in the biological processes: DNA replication initiation; DNA‐dependent DNA replication; chromatin silencing. CG1970‐ NADH dehydrogenase (ubiquinone) activity. It is involved in the biological process mitochondrial electron transport.
