EOG85TG51 GO:0003700 23/75 transcription factor activity, sequence-specific DNA binding molecular_function "Interacting selectively and non-covalently with a specific DNA sequence in order to modulate transcription. The transcription factor may or may not also interact selectively with a protein or macromolecular complex."

In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent."

Visual stimuli are detected in the form of photons and are processed to form an image." [GOC:ai] EOG85TG51 GO:0050896 2/75 response to stimulus biological_process "Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus. The process begins with detection of the stimulus and ends with a change in state or activity or the cell or organism." [GOC:ai, GOC:bf] EOG85TG51 GO:0042067 2/75 establishment of ommatidial planar polarity biological_process "The specification of polarized ommatidia. Ommatidia occur in two chiral forms. The trapezoidal arrangement of photoreceptors in the dorsal part of the eye is the mirror image of that in the ventral part."

An example of this process is found in Drosophila melanogaster."

[PMID:11880339] EOG85TG51 GO:0007460 1/75 R8 cell fate commitment biological_process "The process in which the R8 photoreceptor commits to its cell fate. The R8 receptor contributes the central part of the rhabdomere in the basal parts of the ommatidium."
