Any process that stops, prevents, or reduces the frequency, rate or extent of transcription mediated by RNA polymerase II.

The process whose specific outcome is the progression of the antenna over time, from its formation to the mature structure. The antenna are the sensory structures on the head that are capable of detecting various environmental stimuli.

The activities involved in the mental information processing system that receives (registers), modifies, stores, and retrieves informational stimuli. The main stages involved in the formation and retrieval of memory are encoding (processing of received information by acquisition), storage (building a permanent record of received information as a result of consolidation) and retrieval (calling back the stored information and use it in a suitable way to execute a given task).

The behavior of a male, for the purpose of attracting a sexual partner. An example of this process is found in Drosophila melanogaster.

The regionalization process in which the identity of an animal organ primordium is specified. Identity is considered to be the aggregate of characteristics by which a structure is recognized.

Division of an imaginal disc-derived leg into a series of semi-repetitive parts or segments. The Drosophila leg, for example, has nine segments, each separated from the next by a flexible joint.

Any process that modulates the frequency, rate or extent of R7 differentiation.

The process in which the anatomical structures of the antenna are generated and organized.

Any process that modulates the frequency, rate or extent of dendrite morphogenesis.

Any process that modulates the frequency, rate or extent of rhodopsin gene expression. This includes transcriptional, translational, or posttranslational regulation.

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 xenobiotic compound stimulus. Xenobiotic compounds are compounds foreign to living organisms.

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 an organic cyclic compound stimulus.

The process in which a relatively unspecialized cell acquires the specialized features of the R7 photoreceptor.

Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. 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.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

A protein complex that is capable of associating with DNA by direct binding, or via other DNA-binding proteins or complexes, and regulating transcription.

A protein complex that acts as an aryl hydrocarbon (Ah) receptor. Cytosolic and nuclear Ah receptor complexes have different subunit composition, but both contain the ligand-binding subunit AhR.
